Stop and get medical help
For chest pain or pressure, unusual breathlessness, dizziness or fainting, or a racing or irregular heartbeat during exercise, as our plans advise. The American Heart Association says these need immediate medical evaluation.

Call 999 (911 in the US)
For sudden chest pain or discomfort that doesn't go away, or chest pain with sweating, feeling sick, light-headedness or breathlessness; someone who faints while exercising; palpitations that don't go away, or come with chest pain, breathlessness or feeling faint; a headache that starts suddenly and is extremely painful; or the signs of a stroke, such as a face that has dropped on one side, an arm you can't lift or slurred speech, even if they've stopped. Don't drive yourself to A&E.

Sudden eye symptoms
Call 999 or go to A&E for intense eye pain, a red eye, tenderness around the eyes, rainbow-coloured circles around lights, blurred vision, feeling or being sick, or a headache: these can be glaucoma that has come on suddenly. Sudden loss or blurring of vision after a handstand needs checking the same day, as our handstand guide says.

A fall onto your head
Call 999 if someone has been knocked out and hasn't woken up, can't stay awake, has a fit, has problems with their vision or hearing, has clear fluid coming from their ears or nose, has new numbness or weakness, or has problems with walking, balance, understanding, speaking or writing. Get help from NHS 111 after a head injury if they're being sick, feel dizzy, or take medicine that thins the blood. Don't drive yourself to A&E after hitting your head.

A fall onto your hand
Contact NHS 111 for severe wrist pain, a snap, grinding or popping noise when it happened, a wrist you can't move or hold things with, one that has changed shape or colour, or lost feeling in your hand. Pain at the base of the thumb after a fall onto an outstretched hand needs checking the same day, even if the wrist moves well, as our wrist pain guide says. A teenager whose wrist still hurts the day after handstands, or is swollen, should stop putting weight through their hands and see a GP or sports doctor.

A shoulder that slips
Call 999 or go to A&E if, after a fall, your shoulder looks out of place or has changed shape, or you can't move your arm; don't try to put it back in yourself. See a GP or physiotherapist if your shoulder has partly or fully come out of joint, or you worry it might, or if shoulder pain is getting worse or hasn't improved after 2 weeks of looking after it yourself.

Muscle breakdown after a big session
Same day (call NHS 111, or go to A&E if you feel very unwell): after a big or unusual session, such as many wall walks or handstand push-ups, muscle pain, swelling or weakness far worse than the session explains, and dark pee (red, brown, tea or cola coloured), sometimes starting hours or days later. Dark pee isn't always there, so muscles far sorer, more swollen or weaker than the session explains still need the same-day check. It can be rhabdomyolysis, a breakdown of muscle that can harm the kidneys.

Check before you start
If you haven't exercised for some time or have a medical condition, speak to your GP first, as the NHS advises.
