Bruises and contusions

A contusion is crushed muscle tissue and small blood vessels under intact skin, so blood leaks into the muscle and the fascia around it. In jiu-jitsu they come from knee-on-belly pressure, a shin driven into your thigh during a guard pass, an elbow to the ribs in a scramble, and from being dropped on a hard spot of the mat. The thigh, the ribs, the forearms from blocking grips, and the shins from bumping into legs take most of them.

Symptoms

• A tender, firm spot that hurts when you press it or when the muscle contracts
• Discoloration that appears over a day or two and travels downward with gravity
• Stiffness in the muscle, especially the first morning after training
• Reduced range of motion when the bruise sits in a big muscle like the quadriceps

How serious it is: Most are superficial and settle within days. A deep thigh contusion is graded by how much knee flexion you have twenty four hours later: more than ninety degrees is mild, less than forty five degrees is severe and needs medical review.

Typical time out: A few days for a superficial bruise, two to three weeks for a deep thigh contusion, and longer if bleeding was heavy or knee flexion stayed limited in the first days.

See a doctor if: Get checked if the area becomes tight, hard and increasingly painful with numbness or a limb that feels cold, since that can point to compartment syndrome rather than a simple bruise.

What helps

• Short cooling in the first hours purely for pain, then move on to gentle movement
• Keep the joint moving early within a pain-limited range instead of holding it still
• For a deep thigh bruise, hold the knee in a comfortable bent position early on rather than fully straight
• Return to rolling in stages: drilling first, then positional rounds, then full rounds
• Pad recurring impact points and change the drill that keeps hitting the same spot

Sprains (ankle, wrist)

A sprain is a stretched or torn ligament, the short band that holds two bones together. At the ankle it is usually the anterior talofibular ligament on the outside, twisted when a foot stays caught in a lapel or in your partner’s guard while your body turns. At the wrist it is often the scapholunate ligament or the ulnar side structures, loaded when you post a hand to stop a sweep and your body weight lands on a bent wrist.

Symptoms

• Sharp pain at the moment of the twist, then a duller ache
• Swelling around the joint within a few hours
• Tenderness over one specific spot rather than the whole joint
• The joint feels loose or unreliable when you load it
• Pain when you post on the hand or push off the foot

How serious it is: Sprains are graded one to three: grade 1 is a stretch with mild swelling and full stability, grade 2 a partial tear with clear laxity, grade 3 a complete rupture with an unstable joint that usually needs imaging and specialist care.

Typical time out: One to three weeks for a grade 1, three to six weeks for a grade 2, and three months or more for a grade 3 or when a fracture sits alongside the ligament damage.

See a doctor if: See a doctor if you cannot take four steps on the ankle, if there is bone tenderness at the back edge of the ankle bones, or if the wrist stays swollen and painful in the anatomical snuffbox, which can mean a scaphoid fracture.

What helps

• Load the joint early within a pain-limited range instead of resting it fully
• Balance and proprioception work for the ankle, single leg stance progressing to unstable surfaces
• Grip and wrist strengthening, including loaded extension holds, before you return to posting
• Tape or a wrist wrap for the first weeks back, then wean off as strength returns
• Imaging when pain sits on bone, when instability persists, or when there is no progress after two to three weeks

Strains (muscle)

A strain is a tear in muscle fibers or at the junction where muscle becomes tendon, and it happens when the muscle is lengthening while it contracts. In jiu-jitsu the classic sites are the hamstrings and adductors during an explosive guard retention or a sudden split of the legs in a pass, the neck and upper back muscles resisting a head-and-arm control, and the lower back when you bridge under load.

Symptoms

• A sudden pulling or tearing sensation during a specific movement
• Pain when you stretch or actively contract that muscle
• A tender line or point you can find with your fingers
• Bruising a day or two later if the tear was substantial
• Weakness or a reluctance to load the limb fully

How serious it is: Strains run grade 1 to 3: grade 1 involves a small number of fibers with near normal strength, grade 2 a partial tear with obvious strength loss, grade 3 a complete rupture, sometimes with a visible gap or a lump in the muscle belly.

Typical time out: Two to six weeks for a grade 1, six to twelve weeks for a grade 2, and three months or more for a complete rupture, especially at a tendon attachment where surgery may be considered.

See a doctor if: Seek medical review if you felt a pop with immediate loss of function, if there is a palpable gap in the muscle, or if bruising spreads widely down the limb.

What helps

• Isometric holds within a pain-free range in the first days, then progressive loading
• Eccentric strengthening for hamstrings and adductors as the main protective work
• Build back through the specific position that caused it, at low speed first
• Manage weekly training load, since most strains cluster after a sudden jump in rounds
• Physical therapy if strength or range is not tracking back by three to four weeks

Fractures (hand, foot)

A fracture is a break in bone, and in the hand and foot these are usually the small metacarpals, phalanges and metatarsals, or the scaphoid in the wrist. In jiu-jitsu they come from a finger caught deep in a gi lapel or sleeve while the grip is ripped away, a toe hooked in a pant leg or in the mat seam during a scramble, and from a hand or foot landing awkwardly under body weight in a takedown.

Symptoms

• Immediate sharp pain at one point on the bone
• Swelling that develops fast and spreads across the hand or foot
• A finger or toe that looks crooked or rotated compared to the other side
• Pain when you load the bone, grip, or push off the foot
• Bruising that shows up on the palm or sole within a day

How serious it is: Undisplaced fractures where the bone ends remain aligned are usually treated with immobilization alone. Displaced, rotated, or joint-involving fractures need reduction and sometimes fixation, and a rotated finger is a surgical question because it will otherwise cross over its neighbor when you make a fist.

Typical time out: Four to eight weeks for a simple undisplaced finger or toe fracture with a graded return, and three to six months when there is displacement, surgery, or a scaphoid involved, since the scaphoid heals slowly.

See a doctor if: Go to a doctor the same day if the digit is visibly deformed or rotated, if the skin is broken over the bone, or if you have numbness or a cold, pale finger or toe.

What helps

• Get imaging early, since a missed scaphoid or rotated finger fracture is much harder to fix late
• Follow the immobilization period as prescribed, then start motion work quickly to avoid a stiff joint
• Buddy taping for stable finger fractures once your doctor allows movement
• Grip strength and tendon glide exercises with a hand therapist after immobilization
• Return to gripping in stages: no-gi or open hand work first, then light gi grips, then full grip fighting

Dislocations (shoulder, fingers)

A dislocation means the joint surfaces have come completely apart, tearing or stretching the capsule and ligaments that hold them. The shoulder usually goes forward and down when the arm is pulled back and rotated out, which is exactly the position of a defended kimura or an americana held too long. Finger dislocations happen at the middle joint when a grip is stripped sideways or the fingertip catches in a sleeve.

Symptoms

• Intense pain and a clear sense that the joint moved out of place
• A visibly wrong shape: a squared shoulder, a finger bent at an angle
• You cannot move the joint through its normal range
• Pins and needles or numbness down the arm after a shoulder dislocation
• Rapid swelling around the joint once it is back in place

How serious it is: A first-time shoulder dislocation in a young athlete carries a high risk of recurrence because the labrum is usually torn, which is why specialist review matters. A simple finger dislocation that reduces easily and stays stable is far less serious than one with a fracture at the joint surface.

Typical time out: Six to twelve weeks for a first shoulder dislocation managed without surgery, four to six months after stabilization surgery, and three to six weeks for an uncomplicated finger dislocation.

See a doctor if: Go to an emergency department if the joint is still out of place, if the arm or finger is numb, or if the limb below the injury looks pale or feels cold.

What helps

• Let a clinician reduce the joint rather than pulling on it on the mat
• Short immobilization for comfort, then early guided movement to avoid a stiff joint
• Rotator cuff and scapular strengthening for the shoulder, with special attention to external rotation strength
• Buddy taping and hand therapy for finger joints, since these swell and stiffen for months
• Specialist review after a first shoulder dislocation before you go back to grip fighting or defending kimuras

Cuts and abrasions

Abrasions are the loss of the outer skin layers by friction, and cuts go through the full thickness into the tissue beneath. On the mat they come from gi collar friction on the neck, mat burn on the elbows, knees and toes, an accidental head clash, and a fingernail or toenail catching the face during a scramble. Damaged skin is also the doorway for the infections common in grappling gyms.

Symptoms

• Stinging, raw skin at the contact point
• Bleeding that stops with a few minutes of direct pressure
• Weeping or crusting over the next days
• Increasing redness, warmth or throbbing pain if it is getting infected

How serious it is: Superficial abrasions heal without a scar. A cut that gapes open, keeps bleeding after ten minutes of pressure, or sits over a joint or on the face needs closure by a clinician, ideally within a few hours.

Typical time out: Two to seven days off the mat for most abrasions until the surface is closed, and one to two weeks for a sutured cut, since a wound that reopens under a gi grip heals worse.

See a doctor if: See a doctor if redness spreads outward from the wound, if there is pus, fever, or a red streak running up the limb, or if a cut gapes and will not stay closed.

What helps

• Rinse thoroughly with running water to remove mat grit before you cover it
• Keep the wound covered and moist rather than letting it dry into a hard scab
• Stay off the mat until it is closed, both for your healing and for your partners
• Keep nails cut short and check tournament rules on covering open wounds
• Have your tetanus status checked if a wound is deep or dirty

Concussions

A concussion is a functional disturbance of the brain after a force transmitted to the head, with no structural damage visible on standard imaging. In jiu-jitsu it usually comes from the back of the head hitting the mat during a takedown or a failed sweep, from a knee or head clash in a scramble, and occasionally from staying in a tight choke too long and hitting the mat unprotected.

Symptoms

• Headache or pressure in the head after the impact
• Feeling dazed, slowed down, or as if in a fog
• Dizziness, nausea, or sensitivity to light and noise
• Trouble remembering the moments around the incident
• Sleep problems, irritability, or difficulty concentrating over the following days

How serious it is: Concussion is no longer graded by numbers. What matters is how many symptoms there are, how long they last, and whether there was loss of consciousness or amnesia, since a longer symptom course and repeated concussions predict a slower recovery.

Typical time out: Most people are symptom free within two to four weeks and return through a stepwise protocol, but a first day back to contact should never come before the symptoms have settled at rest and during light exercise, and repeat concussions extend this considerably.

See a doctor if: Go to an emergency department for worsening headache, repeated vomiting, seizure, weakness or numbness in a limb, slurred speech, or drowsiness that makes the person hard to wake.

What helps

• Stop training immediately and do not return the same day, even if you feel fine after a few minutes
• Relative rest for the first day or two, then light aerobic activity below the symptom threshold rather than a dark room for weeks
• A graded return: light cardio, then drilling, then contact, with a day at each step and no symptom flare
• Medical clearance before you go back to live rolling
• Learn and drill breakfalls, since most mat concussions come from an uncontrolled landing

Knee injuries (e.g. ACL tear)

The knee is held by four ligaments and cushioned by two menisci, and jiu-jitsu loads all of them in rotation. The anterior cruciate ligament tears when the foot is planted and the body rotates over it, typically in a takedown or when a leg is trapped in a half guard while you turn. The medial collateral ligament and the medial meniscus take damage from knee reaping, from heel hooks, and from twisting out of a stack pass.

Symptoms

• A pop or tearing feeling at the moment of the twist
• Rapid swelling within a few hours, which usually means bleeding inside the joint
• The knee giving way or feeling like it will collapse when you change direction
• Locking or catching, where the knee will not fully straighten
• Pain along the inner or outer joint line when you kneel or squat

How serious it is: Collateral ligament injuries are graded one to three by laxity, and grade 1 and 2 mostly heal without surgery. A complete ACL tear does not heal back to a competent ligament on its own, and a locked knee suggests a displaced meniscal tear that needs prompt specialist review.

Typical time out: Two to six weeks for a mild collateral sprain, six to twelve weeks for a grade 2, and nine to twelve months after ACL reconstruction before full contested rolling, because return before that carries a high reinjury rate.

See a doctor if: See a doctor if the knee swelled within a couple of hours, if it locks and cannot be straightened, or if it gives way when you walk on flat ground.

What helps

• Get an early assessment, since a swollen unstable knee after a twist needs a diagnosis, not a wait-and-see
• Quadriceps and hamstring strengthening, with hamstring work protecting the ACL specifically
• Progress from straight line loading to controlled rotation before any live rolling
• Neuromuscular control and landing work as part of the rehab, not just strength
• Set clear rules with training partners about heel hooks and knee reaping while you build back

Tendonitis

The term covers tendinopathy, a change in the tendon’s collagen structure from repeated loading that outpaces recovery, rather than simple inflammation. In jiu-jitsu the common sites are the common extensor tendon at the outer elbow from constant gi gripping, the rotator cuff tendons at the shoulder from underhooks and frames, and the wrist flexors and extensors from posting and pummeling.

Symptoms

• Pain that is worst at the start of training and eases as you warm up, then returns worse afterward
• A tender spot right on the tendon or where it meets the bone
• Grip strength that fades and hurts, especially on gi lapels
• Stiffness in the joint in the morning
• Pain when you load the tendon against resistance, not just when you stretch it

How serious it is: Early reactive tendinopathy settles quickly with load management. A long-standing tendon that has been painful for months has structural change inside it and takes far longer, and a tendon that suddenly gives out under a normal load may have partially torn.

Typical time out: You can usually keep training in a modified form throughout. Expect six to twelve weeks of structured loading for a recent case and three to six months when it has been painful for over a year.

See a doctor if: Get it looked at if the tendon suddenly loses power under a normal load, if you have night pain at rest, or if the pain comes with numbness and tingling into the hand.

What helps

• Cut the load that provokes it rather than stopping entirely, since complete rest weakens the tendon further
• Isometric holds for short term pain relief, then progressive heavy slow or eccentric loading as the main treatment
• Grip work with a rolled towel or a thick bar to build tolerance for gi grips
• Switch to no-gi or lighter grip fighting for a block of weeks while you load the tendon in the gym
• Corticosteroid injection is an exception rather than a solution: it helps pain for weeks but outcomes at a year are often worse, so treat it as a bridge and never as the plan

Rib injuries

Rib injuries range from bruised intercostal muscles to a cracked rib to costochondritis, an irritation of the cartilage where the rib joins the breastbone. In jiu-jitsu they come from knee-on-belly, from a heavy stack pass compressing the chest, from a knee driven into the side while you shrimp, and from body triangles and closed guard squeezes.

Symptoms

• Sharp pain on one side when you take a deep breath, cough, laugh or sneeze
• Pain rolling over in bed or getting up from lying down
• A tender point you can find precisely with one finger
• A tight band feeling around the chest when you breathe deeply
• Pain when a partner puts pressure on that side

How serious it is: Muscle and cartilage injuries hurt intensely but are not dangerous. A fractured rib matters mainly for what sits behind it, and multiple broken ribs, breathlessness, or pain over the lowest ribs on the left or right needs urgent assessment because of the spleen and liver.

Typical time out: Three to six weeks for a muscle or cartilage strain, six to twelve weeks for a rib fracture before full contact, and costochondritis can grumble for months if the compressive load keeps coming back.

See a doctor if: Get urgent care if you are short of breath, coughing blood, feel faint, or have severe pain over the upper abdomen after a heavy impact.

What helps

• Keep breathing deeply on purpose several times an hour, since shallow breathing to avoid pain leads to chest infections
• Do not strap or bind the chest, it restricts the breathing you need
• Gentle trunk rotation and thoracic mobility work once the sharp pain has eased
• Return in stages: drilling with no chest pressure, then light positional rounds, then full rounds
• Tell partners which side it is and avoid knee-on-belly and body triangles for the first weeks back

Neck injuries

The cervical spine is seven small vertebrae with discs, facet joints and the muscles that stabilize them, and jiu-jitsu loads all of it. Injuries range from a muscle strain or facet joint irritation after a guillotine or a can opener, to nerve root irritation from a bulging disc, to a stinger where the brachial plexus is stretched when the head is bent one way and the shoulder pushed the other.

Symptoms

• Stiffness and pain that makes turning the head to one side hard
• Pain radiating into the shoulder blade or down one arm
• Burning or electric pain down an arm that fades within minutes after a stinger
• Headache at the base of the skull
• Numbness, tingling or weakness in the hand or fingers

How serious it is: A simple muscular strain settles in days to a couple of weeks. Symptoms into the arm suggest a nerve root and need assessment, and any weakness, symptoms in both arms or legs, or bladder changes after a neck injury is an emergency, not a training question.

Typical time out: One to three weeks for a muscular strain, six to twelve weeks or more when a nerve root is involved, and much longer when there is significant disc or bony injury.

See a doctor if: Go to an emergency department for weakness or numbness in more than one limb, symptoms in the legs, loss of bladder or bowel control, or severe midline neck pain after a hard landing.

What helps

• Keep the neck moving gently early rather than holding it stiff, and skip the collar unless a doctor prescribes one
• Deep neck flexor and scapular strengthening once the acute pain has settled
• Isometric neck work in all four directions as the long term protection for grapplers
• Tap early to neck cranks and stop drilling stacked positions while symptoms are present
• Imaging and specialist review if arm symptoms persist beyond two to three weeks

Back injuries (e.g. herniated disc)

A disc herniation is when the soft inner nucleus of an intervertebral disc pushes through the outer ring and presses on or chemically irritates a nerve root, most often at the two lowest lumbar levels. Jiu-jitsu loads this through repeated flexion under compression: inverting, stacking, bridging out of mount, and lifting an opponent in a takedown with a rounded back.

Symptoms

• Pain in the lower back that can shoot into the buttock and down one leg
• Symptoms worse with sitting, bending forward, coughing or sneezing
• Numbness, pins and needles or weakness in a specific part of the leg or foot
• Difficulty standing up straight, or a lean to one side
• Morning stiffness that takes a long time to loosen

How serious it is: Most disc-related leg pain improves over weeks to months without surgery, because the herniated material shrinks over time. Progressive weakness in a leg, or numbness in the saddle area with bladder or bowel changes, is a different matter and needs immediate care.

Typical time out: Two to six weeks for a mechanical back strain, three to six months for a disc herniation with leg symptoms, longer if surgery is needed, and the range is wide because nerve symptoms settle at very different speeds.

See a doctor if: Get emergency care for numbness in the groin or inner thighs, loss of bladder or bowel control, or a leg that is getting visibly weaker.

What helps

• Stay as active as pain allows and avoid bed rest, since prolonged rest worsens outcomes
• Find and use the directions that ease the leg pain, often extension based positions early on
• Progressive strengthening of hips, glutes and trunk once the acute nerve pain settles
• Learn to hinge at the hips with a neutral spine for takedowns and lifts
• Physical therapy early and imaging only if symptoms persist or there is progressive weakness

Elbow injuries

The elbow is a hinge with almost no rotational tolerance, so it is exactly the joint an arm bar attacks. Forced hyperextension stretches or tears the anterior capsule and the ulnar collateral ligament on the inner side, and can chip the joint surfaces where they slam together. Repetitive gripping instead produces tendinopathy at the outer and inner bony points. In competition the elbow is the most frequently injured joint in Brazilian jiu-jitsu, at 38.9 percent of orthopaedic injuries, and the arm bar is the main mechanism.

Symptoms

• Pain on the inner side of the elbow when the arm is straightened
• The elbow will not fully straighten or fully bend afterward
• Swelling around the joint and a feeling of fullness
• A sense of looseness or apprehension when the arm is extended
• Tingling into the little and ring fingers if the ulnar nerve is irritated

How serious it is: A stretched capsule after a late tap usually settles in a couple of weeks. A partial or complete ulnar collateral ligament tear leaves the elbow loose against valgus stress, and a fracture at the radial head or the tip of the ulna can hide behind what feels like a sprain.

Typical time out: Two to four weeks after a mild hyperextension, six to twelve weeks for a significant ligament injury treated without surgery, and six months or more after ligament reconstruction or a fracture that needed fixing.

See a doctor if: See a doctor if the elbow cannot be straightened at all, if it swells rapidly, or if you have persistent numbness in the ring and little fingers.

What helps

• Regain full extension early with gentle range work, since a stiff elbow is the usual long term problem
• Grip and forearm strengthening, then progressive loading of the elbow in extension
• For gripping tendinopathy, heavy slow loading of the wrist extensors and a break from heavy gi grips
• Tap earlier to arm bars while you rebuild, and tell partners to release slowly rather than at the last inch
• Imaging if the joint locks, if extension does not return, or if there is bony tenderness

Dehydration

Dehydration is a net loss of body water and electrolytes, mostly sodium, through sweat that is not replaced. Jiu-jitsu drives it hard because a thick gi traps heat, rounds are continuous, and many athletes cut weight before competition by restricting fluid, which starts the day already in deficit and reduces both strength and thermoregulation.

Symptoms

• Thirst, dry mouth and dark urine
• Fading strength and grip endurance in later rounds
• Headache and lightheadedness, particularly when standing up
• Muscle cramps in the calves, hands or abdomen
• Feeling unusually irritable or unable to concentrate

How serious it is: Mild dehydration mainly costs performance and comfort. It becomes serious when you stop sweating, feel confused, or faint, since that overlaps with heat illness and needs immediate treatment.

Typical time out: Hours to a day for mild cases once you rehydrate, and several days after aggressive weight cutting or a heat-related collapse before hard training makes sense again.

See a doctor if: Get medical help if someone is confused, stops sweating despite the heat, faints, or cannot keep fluids down.

What helps

• Drink to thirst across the day rather than only at the gym, and include sodium with fluids after heavy sweating
• Weigh yourself before and after a hard session to see how much you actually lose
• Use short breaks between rounds to drink, not just to catch your breath
• Avoid extreme water cuts before competition and work with a coach on a realistic weight class
• Open the gi and cool down between rounds rather than staying wrapped up

Skin infections (due to close contact)

Grappling transmits skin infections by direct contact and shared mats. The main three are tinea corporis, a fungus better known as ringworm, staphylococcal infections including impetigo and boils, and herpes gladiatorum, a viral infection from the cold sore family. Friction from the gi and mat burn breaks the skin barrier, which is what lets the organism in.

Symptoms

• A round, scaly patch with a raised edge and a clearer center for ringworm
• Honey-colored crusts or a spreading red area with pus for a bacterial infection
• A painful cluster of small blisters, often on the face or neck, for herpes gladiatorum
• Itching or burning in the area before anything is visible
• Fever or feeling generally unwell if the infection is spreading

How serious it is: Superficial ringworm responds to topical treatment. A spreading red, hot, tender area with fever suggests cellulitis and needs oral antibiotics, and a painful lump that will not settle can be an abscess that needs draining.

Typical time out: Off the mat until the lesions are healed or your doctor clears you: typically about a week of treatment for ringworm, and longer for bacterial or viral infections, since returning early infects your training partners.

See a doctor if: See a doctor if redness spreads quickly, if you have a fever, if a red streak runs up the limb, or if blisters appear in a painful cluster.

What helps

• Shower immediately after training and wash the gi after every session
• Cover any break in the skin before you step on the mat and stay off when you have an open lesion
• Topical antifungal for ringworm, applied past the point where it looks better, usually a week or two longer
• See a doctor early for anything blistering, spreading or painful rather than treating it blindly
• Push your gym to clean mats daily, since one uncleaned mat undoes everyone’s hygiene

Heat-related illnesses (heat stroke)

Heat illness runs from heat exhaustion, where the circulation cannot support both the working muscles and skin cooling, to heat stroke, where the core temperature rises above roughly 40 degrees Celsius and the brain and other organs start to fail. A gi is effectively insulation, continuous rounds give no cooling window, and a poorly ventilated gym in summer makes it far more likely.

Symptoms

• Heavy sweating followed by weakness, nausea and a pounding headache
• Dizziness or feeling faint when you stand
• Skin that is hot and either soaked or unexpectedly dry
• Confusion, slurred speech or behaving oddly, which points to heat stroke
• A racing pulse that does not settle when you stop

How serious it is: Heat exhaustion improves with cooling and fluids. Heat stroke is defined by an altered mental state with a high core temperature and is a medical emergency where minutes of delay in cooling change the outcome.

Typical time out: A day or two after heat exhaustion with a careful return, and several weeks with medical clearance after heat stroke, since heat tolerance stays reduced for a while afterward.

See a doctor if: Call emergency services immediately for confusion, collapse, seizure or unresponsiveness in the heat, and start cooling while you wait.

What helps

• Get the person into shade or air conditioning, strip the gi, and cool aggressively with cold water and ice packs to the neck, armpits and groin
• Cool first, transport second, if heat stroke is suspected
• Build heat tolerance gradually over one to two weeks at the start of summer rather than all at once
• Plan drink breaks into rounds and open the gi between them
• Push for fans, ventilation and shorter rounds when the gym is hot

Cauliflower ear

Repeated friction or a direct blow shears the perichondrium, the thin layer that feeds the ear cartilage, away from the cartilage itself. Blood fills the gap as an auricular hematoma, and if it is not drained, it organizes into fibrous tissue and new cartilage, which is the permanent lumpy shape. In jiu-jitsu it comes from head pressure in guard passing, from the ear grinding on the gi during a triangle or head-and-arm control, and from repeated scrambles.

Symptoms

• A hot, swollen, soft lump on the outer ear after training
• Throbbing pain and tenderness to touch
• The normal folds of the ear look flattened and filled in
• Discomfort when lying on that side or wearing headphones

How serious it is: A fresh, soft hematoma is treatable and the ear can look normal again if it is drained early, usually within the first few days. Once it firms up, the change is permanent and only surgery alters the shape. Any hematoma can also become infected, which threatens the cartilage itself.

Typical time out: A few days to two weeks off head-contact work after drainage while compression stays in place, and repeated drainage over several weeks if it refills.

See a doctor if: See a doctor promptly if the ear becomes increasingly red, hot and painful with fever, since an infected ear cartilage can be destroyed quickly.

What helps

• Get a fresh hematoma drained early by a clinician rather than draining it yourself, since a home needle is the usual route to infection
• Wear compression after drainage exactly as long as advised, because it refills easily
• Wear ear guards during hard rounds if you want to keep the shape of your ears
• Short cooling right after the impact to limit the initial bleeding
• Change the drills that keep grinding the same ear, and accept that repeated episodes on one ear will eventually stay

First Aid for Soft Tissue Injuries: PEACE and LOVE

Sports medicine has moved on from RICE. The current guidance, published in the British Journal of Sports Medicine in 2019, splits care into the first days after the injury and everything that follows.

PEACE, the first two to three days

• Protect: unload the area and limit movement that hurts, but only briefly.
• Elevate: keep the limb above heart level when you can.
• Avoid anti-inflammatories: they may blunt the healing you need.
• Compress: a bandage or taping limits swelling.
• Educate: your body heals this on its own; passive treatments rarely speed it up.

LOVE, from day three onward

• Load: return to movement as pain allows, early loading builds tissue.
• Optimism: expectations shape recovery more than most people assume.
• Vascularization: easy cardio that does not hurt brings blood to the area.
• Exercise: restore strength, mobility and balance before returning to play.

Ice still helps with pain in the first hours. What changed is the evidence that long icing and routine anti-inflammatory drugs slow tissue repair.

How to Lower Your Risk in Brazilian Jiu Jitsu

• Tap early to elbow locks and leg entanglements. The elbow is the most injured joint in competition at 38.9 percent of orthopaedic injuries, and nearly all of that is a late tap to an arm bar.
• Train the neck directly with isometric holds in all four directions, since guillotines, stacks and can openers load the cervical spine every single session.
• Build grip and forearm endurance off the mat with towel hangs and thick bar work, so gi gripping stops being the thing that creates elbow and wrist tendinopathy.
• Strengthen hamstrings and hips eccentrically and learn to hinge with a neutral spine, which protects both the knee in scrambles and the lower back during takedowns and lifts.
• Drill breakfalls and controlled landings regularly, since the head, shoulder and rib injuries mostly come from how you hit the mat, not from the technique itself.
• Manage weekly load rather than intensity alone: add rounds gradually, keep at least one lower intensity day, and choose partners deliberately, since competitors 16 and older are injured at 10.8 per 1,000 exposures compared with 4.1 for those 15 and under.

When to Stop and Get Medical Help

Most of the injuries on this page are treated at home. These signs are not.

• Any suspected fracture: a visible deformity, a rotated finger or toe, bone that is tender at one point, or an inability to bear weight.
• A head impact with confusion, memory loss, repeated vomiting, a seizure, or drowsiness that makes the person hard to wake.
• Numbness, tingling or weakness in an arm or leg after a neck or back injury, and especially any symptoms in both limbs or in the legs.
• A joint that is stuck and cannot be moved or straightened, or a joint that is still visibly out of place after a dislocation.
• Signs of heat stroke: confusion, collapse or unresponsiveness in a hot gym. Start cooling immediately and call emergency services.
• A spreading red, hot skin area with fever or a red streak running up a limb, which suggests a spreading infection rather than a simple mat burn.
