Warning signs: when to stop and get help
These are the warning signs from our sprinting, hamstring strain, hamstring injury yoga, back pain and yoga guides, word for word, with one line of our own. This is general information, not a diagnosis. A&E means accident and emergency; in the US, call 911 for 999.
A hamstring injury
The NHS says you may feel a sharp pain in the back of your leg, and with a severe injury a snapping sensation or a pop. Get help from NHS 111 if it's very painful or getting worse, there's a large amount of swelling or bruising, it hurts to walk or stand on the leg, or it isn't getting better after treating it yourself. A pop near the sitting bone with a big bruise high on the thigh needs checking the same day, as our hamstring strain guide explains.

Same day
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.

Teenagers
Same day, for an X-ray (our suggestion): a teenager with sudden pain at the sitting bone after a sprint, a kick or the splits, often with a pop, especially if walking or sitting hurts. While the bones are still growing, the tendon can pull off a piece of bone.

See a GP or physiotherapist
Pain in the back of the thigh with tingling, numbness, or pain spreading below the knee: it may come from the back (sciatica).
Deep pain low in the buttock with sitting and running that is not settling: possible high hamstring tendinopathy, which has its own guide.

Back pain: call 999 or go to A&E
Call 999 or go to A&E: loss of feeling or numbness around the genitals or bottom, new trouble peeing or controlling your bladder or bowels, changes in genital sensation during sex or problems with erections or orgasm, or pain, tingling, weakness or numbness in both legs. These are signs of cauda equina syndrome, which needs treating in hospital urgently. Don't drive yourself.
Call 999 or go to A&E: back pain with chest pain, or back pain that started after a serious accident, such as a car crash.

Back pain: get help the same day
Same day (GP or NHS 111): back pain and you feel hot, cold, shivery or generally unwell, or severe pain that starts suddenly or is getting worse quickly.
Same day: leg weakness that is getting worse.

Back pain: see a GP
Back pain that hasn't improved after a few weeks of looking after it at home, stops you doing day-to-day activities, worries you, or you're struggling to cope.
Pain that doesn't improve with rest or is worse at night, or pain that is worse when you sneeze, cough or poo.
Back pain and stiffness that persists in a teenager or young adult. Ankylosing spondylitis tends to start at that age and can affect the whole spine.
Back pain that started before 45 and has lasted more than 3 months, especially if it started before 35, wakes you in the second half of the night, comes with buttock pain, gets better with movement or within 48 hours of anti-inflammatory painkillers, or you have or have had arthritis, pain where a tendon attaches to bone (enthesitis) or psoriasis, or a parent, brother, sister or child with spondyloarthritis. These can point to inflammatory back pain (axial spondyloarthritis, such as ankylosing spondylitis). The National Institute for Health and Care Excellence (NICE) asks GPs to refer people with 4 or more of these 9 features to a rheumatologist, and to do a blood test for the HLA-B27 gene marker if exactly 3 are present, referring if it is positive.

A young sprinter's back (our suggestion)
A teenage or young adult sprinter or hurdler with low back pain that's worse when arching backwards or twisting, or that keeps coming back, should see a GP or sports physiotherapist before more backbends or block starts, because a stress fracture of the spine (spondylolysis) is possible.

A snap at the back of the ankle
A sudden snap or pop at the back of the ankle, or not being able to stand on tiptoe, can mean a ruptured Achilles tendon. The NHS says to get help from NHS 111 if you think you've ruptured a tendon, and our Achilles rupture guide explains why it's urgent.

Pain in one spot on a bone
Pain on a bone that's worse when you run or jump and hurts when pressed can be a stress fracture. Stop and get it checked, as our stress fracture guide explains.

Fainting or chest pain: call 999
Call 999 if someone faints while exercising, or has sudden chest pain or discomfort that doesn't go away.
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.
With glaucoma, or high blood pressure that isn't under control, skip headstands, shoulder stands and long head-down holds. With osteoporosis, swap deep forward folds for a flat-back hinge from the hips, and twist smoothly. In pregnancy, our yoga in pregnancy guide covers the changes. NCCIH advises beginners to avoid headstands, shoulder stands, the lotus position and forceful breathing.

Before you start
The NHS advises getting advice from a healthcare professional first if you have a health problem, an injury or symptoms, or have recently had a heart attack or an operation.
