Warning signs: when to get help
These follow our Pilates for footballers, football and ankle sprain guides word for word. This is general information, not a diagnosis. A&E means accident and emergency; in the US, call 911 for 999.
A pop at the back of the thigh
Same day: a pop near the sitting bone, a large bruise high on the back of the thigh, or you cannot put weight on the leg. The tendon may have pulled away from the bone, which needs assessing before you start these exercises.
Get help from NHS 111 if you think you've injured your hamstring and it's very painful, or the pain is getting worse; there's a large amount of swelling or bruising, or the swelling or bruising is getting worse; it hurts to walk or stand using the injured leg; your leg feels very stiff or is difficult to move; it's not feeling any better after treating it yourself; or you have a very high temperature or you feel very hot, but also cold and shivery, which could be signs of an infection.

A pop high on the inner thigh
A pop high on the inner thigh, then a large bruise, a dent or a gap you can feel, and weakness squeezing the legs together, can be a complete tear of the adductor longus tendon: get it checked within days, as our inner thigh pain guide says.
A knee injury
Go to A&E (accident and emergency) if you've injured your knee and it has changed shape, it becomes very swollen very quickly, you felt a pop or snap, you can see bone sticking out, or it's bleeding heavily. Don't drive yourself: ask someone to take you, or call 999 if the pain means you can't move your leg to get there.
Get advice from NHS 111 now: you cannot move the knee or put any weight on it, or it is very painful, badly swollen or has changed shape, or it locks, gives way or clicks painfully. A pop, quick swelling and a knee that gives way point to an ACL injury: our ACL injury guide says what to do.

An ankle injury
Call 999 or go to A&E: after an injury, you heard a crack, the foot or ankle has changed shape or points at an odd angle, a bone is sticking out, there is a bad cut over it, you're in severe pain, or the toes look blue or white, feel numb or are cold to touch. These can mean a broken bone. Don't drive yourself.
Same day (NHS 111 or an urgent treatment centre): after an injury, you can't put weight on it or walk more than a few steps, the pain is very bad or getting worse, there is a lot of swelling or bruising or it is getting worse, it feels very stiff, or it's not feeling any better after treating it yourself. Get the same help if you also have a very high temperature, or feel hot, cold or shivery: this could be an infection. If you think it's broken, don't treat it yourself.

A head injury
Call 999 if someone has hit their head and has been knocked out and hasn't woken up, can't stay awake or keep their eyes open, has a fit, has fallen from a height of more than 1 metre or 5 stairs, has problems with their vision or hearing, has clear fluid coming from their ears or nose, has new numbness or weakness, has problems with walking, balance, understanding, speaking or writing, hit their head at high speed, or their behaviour has changed. Get help from NHS 111 if they're being sick, feel dizzy or take medicine that thins the blood. If you're told to go to A&E (accident and emergency), don't drive yourself there if you have hit your head.
With a suspected concussion, if in doubt, sit them out. The UK's grassroots guidelines say no sport for at least 24 hours, get checked by a healthcare professional or NHS 111 within 24 hours, follow a staged return, and no competition before day 21; if symptoms last beyond 28 days, stay out of sport and see a doctor. Yoga waits too: gentle breathing fits the early, light-activity stages, and no head-down poses or inversions until you're cleared (our reading). Our concussion guide has the stages.

Chest pain or fainting while exercising: 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 practice
Stop a stretch at the first sharp pull high at the back of the thigh or in the groin, and "Ease off a deep fold, lunge or twist that brings a sharp pinch deep in the groin" (our hip openers guide).
