Warning signs: when to get help
These are the warning signs from our Achilles, heel and ankle 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 snap at the back of the heel
Same day: a sudden snap or pop at the back of the heel or calf, or a feeling of being kicked there, then walking flat-footed and being unable to push off, stand on tiptoe or climb stairs. It could be an Achilles tendon rupture or a broken heel bone. Go to A&E or a minor injuries unit, or contact NHS 111.

One swollen, throbbing calf
Same day (urgent GP appointment or NHS 111): throbbing pain in one leg (rarely both), usually the calf or thigh; swelling in one leg (rarely both); red, blue or darkened skin around the painful area, which may be harder to see on brown or black skin; or swollen veins. This can be a deep vein thrombosis (DVT). It is more likely after surgery, a hospital stay, 3 or more days in bed, a journey of over 4 hours, pregnancy or a recent birth, cancer, a previous clot, or contraception or hormone replacement therapy (HRT) that contains oestrogen.
Ask for an urgent GP appointment or get help from NHS 111: sudden swelling, redness, heat and pain in the calf, which could be a blood clot. Go to A&E: severe pain after an injury, which can mean a broken bone; or you cannot put any weight on the leg.

Breathless or chest pain: call 999
Call 999 or go to A&E if breathing suddenly becomes difficult, if pain in your chest or upper back comes on suddenly with breathlessness or a very fast heartbeat, or if someone passes out. Do not drive yourself. It can be a blood clot that has reached the lungs.

A hot, swollen heel
Same day: the back of the heel is red, hot, swollen and very painful, especially with a high temperature or feeling hot, cold or shivery. It could be an infected bursa or a skin infection.

On an antibiotic
Contact your doctor straight away if your Achilles tendon becomes painful or swollen while you're taking a fluoroquinolone antibiotic (such as ciprofloxacin, levofloxacin, moxifloxacin or ofloxacin), or in the months after. The UK medicines regulator (MHRA) advises stopping the antibiotic at the first sign and resting the painful area until you've been seen; the risk is higher over 60, with kidney problems, after an organ transplant and with steroid medicines.
See a GP or physiotherapist
- Achilles pain that hasn't improved within 12 weeks of following this advice, or is getting worse: talk to a healthcare professional. In many areas you can refer yourself to physiotherapy.
- Pain that is getting worse week on week despite cutting back, or is stopping your normal activities.
- New or worse pain at the back of the heel after a steroid injection near the Achilles tendon: get it checked, because injections there carry a risk of rupture.
- Swelling in several joints, or morning stiffness that lasts more than 30 minutes: see a GP. It can be an inflammatory arthritis such as rheumatoid arthritis rather than osteoarthritis.

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.

Unusual breathlessness
Call 999 or go to A&E (accident and emergency) straight away for severe difficulty breathing (gasping, choking or not able to get words out), a chest that feels tight or heavy, pain that spreads to your arms, back, neck and jaw, lips or skin turning very pale, blue or grey, or sudden confusion. If you're more short of breath than usual, or your heart is racing, fluttering or skipping beats, contact NHS 111.
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.
Come out of a pose for a sharp pain at the back of the heel rather than a dull ache (our suggestion).
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.
