A broken bone, or a clot in the lungs: call 999
- 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.
- 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 suddenly cold, pale foot: call 999
Call 999 or go to A&E: a foot or leg that is suddenly cold, pale, numb, weak or very painful without an injury. A sudden loss of blood supply is a vascular emergency.
Not being able to put weight on it: the same day
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.
Contact NHS 111: after an injury, severe ankle pain, feeling faint, dizzy or sick from the pain, a snap, grinding or popping noise at the time of the injury, the ankle or foot at an odd angle, or not being able to walk. These might be signs of a broken ankle or an infection.

A snap at the back of the heel: the same day
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 ankle or leg: the same day
Ask for an urgent GP appointment or get help from NHS 111 if you have swelling in 1 ankle, foot or leg and you don't know what's causing it; a lot of swelling after an injury, or swelling that is getting worse; swelling that is severe, painful or starts very suddenly; swelling in other parts of your body too, such as your face or tummy; a swollen area that is red or feels hot; a very high temperature, or you feel hot, cold or shivery; or diabetes and swollen feet or ankles. Call 999 if you also feel short of breath or are struggling to breathe, your chest feels tight, heavy or painful, you're coughing up blood, your heartbeat is more noticeable (palpitations), or you feel lightheaded, faint, confused, sick or clammy.
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. It could be a blood clot (DVT). Watch for it after an ankle injury or time in a cast or boot.
Same day: in a cast or boot, pain that is getting worse, toes that are numb or burning, a cast that feels too tight, toes that are swollen, blue or white, or a bad smell from under the cast.

Both ankles swollen: see a GP
Both ankles, feet or legs swollen, and it hasn't improved after a few days of looking after it at home, it gets worse, or you have a condition that affects your heart, kidneys or leg veins: see a GP.

See a GP or physiotherapist
- Pain that isn't better after 2 weeks of looking after it yourself, is getting worse, keeps coming back, or stops you doing normal things.
- An ankle that keeps giving way months after a sprain.
- Pain or swelling still there 6 to 12 weeks after a sprain, or deep pain inside the joint with catching or locking: see your GP. A damaged patch of cartilage and bone on the talus (an osteochondral lesion) is one cause, X-rays often miss it, and it has its own guide.
- Tingling or loss of feeling in the foot, or a foot that feels weak.
- Any foot pain if you have diabetes: foot problems can be more serious.

- 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.

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.

Stop and get medical help
If you get chest pain or pressure, feel faint or dizzy, are unusually breathless, or your heart races or beats irregularly during exercise, as our plans advise.
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.
You can say no to any hands-on adjustment, and a teacher registered with Yoga Alliance must get your explicit consent each time.

Head-down poses, bones and pregnancy
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.
If you have a heart, lung or joint condition, are pregnant or have recently been unwell, start gently and read our guide for your condition. Muscle soreness for a day or two after a new exercise is common and fades as you repeat it.
If you have a heart condition, follow your cardiac team's advice on how hard to work, and stop for the warning signs above. People with long-term conditions may wish to ask their specialist before starting. With uncontrolled high blood pressure, avoid straining against a held breath; the high blood pressure guide has more.
