A broken bone or a crushed, tight thigh: call 999
- Call 999 or go to A&E: you heard a crack when you were injured, the thigh has changed shape or the leg points at an odd angle, the leg is numb or tingling, or the skin has changed colour or is cold to touch. You may have broken a bone. Don't drive yourself.
- Call 999 or go to A&E: sudden, severe pain in a thigh muscle, which may be worse when you stretch it (for example bending the knee), with swelling, numbness, weakness or pins and needles, or tightness or difficulty moving the leg. This can be acute compartment syndrome, which needs surgery as soon as possible. In the thigh it usually follows a heavy knock, a crush or a broken bone. Do not drive yourself to A&E.

Leg pain with breathlessness: call 999
Leg pain or swelling with breathlessness or chest pain: call 999 or go to A&E, and do not drive yourself. It can be a blood clot that has reached the lungs.

A lump at the top of the thigh with severe pain
Call 999 or go to A&E now if you have a femoral hernia (a small lump at the top of your thigh, in your groin) and very bad tummy pain, you feel sick or you're being sick, you cannot fart or poo, you have a high temperature or you feel hot, cold or shivery, or you've suddenly become confused. Do not drive to A&E. With any other hernia and pain in or around it, a bloated tummy, feeling or being sick, vomiting blood or vomit that looks like coffee grounds, constipation, a high temperature or feeling hot, cold or shivery, or sudden confusion, get help from NHS 111.

A very painful or swollen thigh: the same day
Same day (NHS 111): the thigh is very painful or the pain is getting worse, there's a lot of swelling or bruising or it's getting worse, you can't put any weight on the leg or walk more than a few steps, it feels very stiff, or you have a very high temperature or feel hot, cold or shivery.
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 above the kneecap: the same day
Same day: a pop just above the kneecap, then you can't straighten your knee or lift the straight leg, or there's a dent above the kneecap. This can be a quadriceps tendon tear, which almost always needs surgery and does better if it's repaired soon. Our torn kneecap tendons guide covers that injury.
A sudden pain or pop during a pose
Stop if you feel a sudden sharp pain, a snap or a pop in a muscle during a pose: it may be a strain. Get help from NHS 111 if it's very painful or getting worse, there's a lot of swelling or bruising, you can't put weight on it or walk more than a few steps, or it feels very stiff. Our hamstring strain guide has more.

One swollen, throbbing leg: the same day
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; or swollen veins. It may be a blood clot (deep vein thrombosis, DVT).

See a GP or physiotherapist
- Not feeling better after 2 weeks of looking after it yourself, or getting worse: see a GP or physiotherapist.
- A second strain in the same place: ask a physiotherapist to review your rehab.
- A hard, painful lump in the thigh that stays or grows weeks after a knock: bone can form in a bruised muscle (myositis ossificans).
- Front-of-thigh pain with tingling or numbness, or with back pain: it may come from a nerve rather than the muscle.

A lump in the groin or upper thigh
A lump in the groin, upper thigh or tummy, especially one that appears when you cough or strain and goes when you lie down: see a GP, as it may be a true hernia. A femoral hernia (a small lump at the top of the thigh, mainly in women over 50, though it can happen to anyone) needs treating in hospital.

Painful, heavy legs that bruise easily: see a GP
- your legs (and sometimes arms) are out of proportion with the rest of your body, feel painful, tender or heavy, and bruise easily: it could be lipoedema

Eating, weight and body image
The NHS lists spending a lot of time worrying about your weight and body shape, eating very little food, exercising too much, and having very strict routines around food among the signs of an eating disorder, and says to see a GP as soon as you can. Worrying a lot about one area of your body can be body dysmorphic disorder. Beat's helpline in England is 0808 801 0677, and our eating disorders guide has the other numbers.

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.

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.
Your knees during practice
Short stances, knees in line with your second toe, shallow bends at first, never a foot pressed into the side of the knee, and leave out hero pose, lotus and deep squats while a knee is sore (our editorial suggestions). Our yoga for knee pain guide has more.
Breathe out through every effort, especially with high blood pressure, heart disease, glaucoma or diabetic eye disease, a hernia, or in pregnancy (our guide to getting stronger). With glaucoma or uncontrolled high blood pressure, skip headstands, shoulder stands and other full inversions, and keep other head-down poses brief or supported.
After a strain
The NHS: "Avoid strenuous exercise such as running for up to 8 weeks, as there's a risk of further damage." Its hamstring page adds: stop any sport or exercise "if you start to feel pain in your hamstrings".
Sources 54, 58
Stretch to a pull, not a pain
Stretch to a clear pull in the muscle, never a pain in the knee or a pinch at the front of the hip (our suggestion). The strap hamstring stretch's page says: "Burning, tingling or pins and needles down the leg is a nerve signal, not a stretch; back off and have it looked at."

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.
