A head injury with red flags: call 999
The UK guidelines call these red flags, needing urgent assessment by a healthcare professional or at A&E (accident and emergency), by ambulance if necessary.
- Any loss of consciousness, or getting drowsier
- No memory of events before or after the injury
- Increasing confusion or irritability, or unusual behaviour
- New problems understanding, speaking, reading or writing, less feeling, loss of balance, weakness or double vision
- A seizure, twitching limbs, or lying rigid or motionless
- A severe or worsening headache, repeated vomiting or severe neck pain
- A suspected skull fracture: a cut, bruise, swelling or severe pain where they were hit
- Previous brain surgery, a bleeding disorder, blood-thinning medicine, or being drunk or on drugs at the time

A head injury: NHS 111 or a GP
The NHS says to get help from NHS 111 if, after a head injury, you're being sick, feel dizzy, take medicine that thins your blood, were drinking alcohol or taking drugs at the time, or have any other symptoms you're worried about. See a GP if symptoms last more than 2 weeks, and don't play contact sports for at least 3 weeks.

Neck and spinal cord
Numbness, tingling, burning or weakness in both arms, in more than one limb, or in the legs: keep the player still and call 999. It can be an injury to the spinal cord, even if it passes in minutes.
Call 999 or go to A&E: new problems walking, loss of bladder or bowel control, or a sudden loss of coordination, such as difficulty doing up buttons. These can be signs of pressure on the spinal cord.
A hand that looks wrong, or a cut knuckle
Call 999 or go to A&E after an injury (don't drive yourself) if the arm, wrist or hand is numb, tingling or has pins and needles; a bone is sticking out or a bad cut is bleeding heavily; or the wrist, thumb or a finger has changed shape, is at an odd angle, or has turned blue, grey, white or cold.
Same day, urgently: any cut or graze over a knuckle after a punch that hit someone's teeth (a fight bite), however small it looks. Go to A&E, or get help from NHS 111 if you're unsure where to go, and say how it happened. It can look harmless for a few days while infection gets into the joint, and hand surgeons treat it as urgent.
Same day (NHS 111): severe pain in the back of the hand; a snap, grinding or popping noise at the time of the injury; you can't move the hand or hold things; you've lost feeling in part of the hand; the hand has changed shape or colour; or you feel hot, cold or shivery. These can be signs of a broken hand or an infection.
Fingers and wrists after a punch
The NHS says to go to A&E if a finger points at an odd angle, looks blue or feels numb, or bone is showing, and to get help from NHS 111 if it's painful, swollen and bruised or hard to move. A cut over a knuckle from a punch that hit someone's teeth needs help the same day, as our broken hand guide explains.
Get help from NHS 111 for severe wrist pain, a snap, grinding or popping noise at the time of injury, a wrist you can't move or use to hold things, a change in its shape or colour, or lost feeling in your hand. Pain at the base of the thumb after a punch or a fall needs checking for a scaphoid fracture.

A shoulder that looks out of place
Call 999 or go to A&E: after a fall or injury, your shoulder looks out of place or has changed shape, you cannot move your arm, or your shoulder is painful, bruised or swollen. Do not drive yourself, and do not try to put it back in yourself.

Get your shoulder assessed before end-range poses
- Your shoulder has partly or fully come out of joint, or you worry it might.
Flashes, floaters or a shadow in your vision
Get help from NHS 111 if floaters suddenly appear or increase, you see flashes of light, a dark curtain or shadow moves across your vision, or your sight suddenly blurs. These can be signs of a detached retina.
Hot classes and making weight
Our editorial advice: don't use hot yoga, saunas or sweat suits to make weight. In any hot class, drink before and during, and stop at the first sign of dizziness, a headache or feeling sick; our hot yoga guide gives the NHS signs of heat exhaustion and heatstroke.

Chest pain or fainting: call 999
Call 999 if:
- You get sudden pain or discomfort in your chest that doesn't go away; it can feel like squeezing or pressure, burning or indigestion.
- The pain spreads to your left or right arm, or your neck, jaw, stomach or back.
- You have chest pain and feel sweaty, sick, light-headed or short of breath.
- Someone faints while exercising, can't be woken within 1 minute, or has chest pain or a pounding, fluttering or irregular heartbeat.

During yoga
A joint pain that is sharp, gets worse during a session, lingers into the next day or changes how you move is a reason to use an easier version, and to see a GP or physiotherapist if it keeps happening (the rule in our plans). Muscle soreness for a day or two after something new is normal. In a hot class, stop if you feel dizzy, sick or unwell; our hot yoga guide lists the signs of heat illness.
If you're hypermobile, don't use mobility work to push further: the NHS says "do not overextend your joints just because you can". See a GP if you think you have joint hypermobility syndrome: for example, your joints keep dislocating, or you keep getting sprains, strains, pain or stiffness.
Stop for sharp pain, a feeling that the shoulder is slipping, pins and needles or numbness down the arm, or pain that is still worse by your next session after strengthening.
Tell your teacher about any recent knockout or hand injury (our suggestion).
