Warning signs: when to get help
These are the site's lines from our exercise for men, older men, back pain and other guides, word for word, with the NHS's own words where the site has no line. This is general information, not a diagnosis. A&E means accident and emergency; in the US, call 911 for 999, and use your doctor's urgent line or urgent care for NHS 111.
Call 999
Stop exercising and call 999 if any of these happen. Don't drive yourself to A&E.
- Chest pain that feels tight or like squeezing, or spreads to your arms, neck, jaw, back or stomach.
- Chest pain with feeling sweaty, sick, light-headed or short of breath.
- Severe difficulty breathing, or lips or skin that look pale, blue or grey.
- Someone faints while exercising, or faints with chest pain or a pounding, fluttering or irregular heartbeat.
- Palpitations that don't go away, or that come with chest pain, shortness of breath or feeling faint.
- A stomach ache and you cannot pee at all.

Back pain: call 999
- 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: sudden, severe pain in the tummy or back, which can come with breathlessness, pale or grey skin, or collapse. It can be a burst abdominal aortic aneurysm, most common in men aged 65 or over and in people who smoke or used to smoke.

Call NHS 111 or get an urgent GP appointment

See a GP soon
- Erection problems that keep happening. A sexual health clinic can help too.
- A low sex drive, low mood, loss of muscle or of your ability to exercise, tiredness or poor sleep: your GP will look for the cause.
- Trouble peeing, needing to pee more often, or worry about your risk of prostate cancer.
- Palpitations that keep coming back or last more than a few minutes, or if you have fainted.

Erection problems
The NHS says erection problems that keep happening "might be a sign of a health condition that can be treated", such as high blood pressure, high cholesterol or diabetes, so see a GP or a sexual health clinic too.

Back pain that isn't settling
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.

Prostate cancer risk
Prostate Cancer UK: "Prostate cancer mainly affects men over 50, and your risk increases as you get older." and "If you’re Black or have a family history of prostate cancer, you are at a higher risk of getting prostate cancer from the age of 45." If that's you, talk to your GP.

Check with a GP
- Before you start, if you haven't exercised for some time, or you have heart disease or another medical condition.
- If new symptoms appear as you do more.

Start with your GP or cardiac team if
You have heart disease, get chest pain, breathlessness or dizziness on effort, or are having treatment for prostate cancer, as our exercise for men guide advises. After a heart attack, follow your cardiac rehabilitation team.
Stop and rest if you feel
Dizzy, faint, unusually breathless, or sharp or increasing pain. Sit down until it passes, and see a GP if you keep getting dizzy or faint when you stand up.

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.
