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.

Chest pain that comes and goes
Get help from NHS 111: pain or tightness in your chest, neck, shoulders, jaw or arms that comes and goes, often brought on by exercise, stress, emotion or cold and easing after a few minutes' rest. It can be angina, a sign of a heart problem. If you've been diagnosed with angina, get help from NHS 111 too if it feels worse than before, is happening more often, lasts longer or happens when you're resting.

Your heart on duty
Heart attacks and other cardiovascular events are the leading cause of firefighters' deaths on duty: 58% of US deaths on duty in 2024, most often during or soon after fire suppression, alarms or physical training, and usually in firefighters with heart disease they may not have known about. Keep up your service's medicals, and get chest pain, breathlessness or palpitations on exertion checked rather than training through them (our suggestion).

Heatstroke: call 999
The NHS says to call 999 for signs of heatstroke: still being unwell after 30 minutes of resting somewhere cool, being cooled and drinking; a very high temperature; hot skin that isn't sweating; a fast heartbeat; fast breathing or breathlessness; confusion and lack of coordination; a seizure; or loss of consciousness.
Heat exhaustion should improve within 30 minutes of resting somewhere cool, cooling down and drinking. Call 999 if it doesn't, or for a very high temperature, hot skin that isn't sweating, a fast heartbeat, fast breathing, confusion, a fit or loss of consciousness.

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.

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.
- Same day (urgent GP appointment or NHS 111): new difficulty lifting the front of your foot or toes (foot drop), or a foot that slaps down or catches as you walk, especially if it is getting worse. Weakness in both legs, or with numbness around the genitals or bottom or bladder or bowel changes, is the 999 emergency above.

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.
- Unexplained weight loss, or a lump, swelling or change in the shape of your back.
- Pain that doesn't improve with rest or is worse at night, or pain that is worse when you sneeze, cough or poo.
- Pain at the top of the back, between the shoulders, rather than in the lower back.

During Pilates: the back pain rule
Some discomfort during exercise is fine, and it does not mean you are doing damage: the WHO counts "hurt does not necessarily mean harm" among the messages people with back pain need. Aim for pain you would call mild to moderate, no more than about 5 out of 10. It should settle within an hour or so, and your back should be no worse the next morning. If it is worse, do less next time (fewer reps, a smaller range, a lighter load), not nothing.
Leg symptoms are the exception: stop or shrink any movement that sends pain, pins and needles or numbness further down your leg. If leg symptoms move back towards your spine, that is a good sign, even if your back aches a little more for a while.

A shoulder injury
Call 999 or go to A&E: after a fall or injury, your shoulder looks out of place or has changed shape, you cannot move your arm, or your shoulder is painful, bruised or swollen. Do not drive yourself, and do not try to put it back in yourself.
Same day (GP or NHS 111): sudden or very bad shoulder pain; you cannot move your arm; the arm or shoulder is badly swollen or has changed shape; pins and needles that do not go away; no feeling in the arm; the arm is hot or cold to the touch; pain that started after an injury such as a fall; or severe pain in both shoulders.
Same day (GP or NHS 111): sudden weakness lifting the arm after an injury or fall. A rotator cuff tear caused by an injury needs urgent referral to a shoulder specialist. After a dislocation in anyone over 40, the rotator cuff should be checked: about 40% have a tear.
See a GP or physiotherapist if:
- Your shoulder has partly or fully come out of joint, or you worry it might.

A knee injury
Go to A&E (accident and emergency) if you've injured your knee and it has changed shape, it becomes very swollen very quickly, you felt a pop or snap, you can see bone sticking out, or it's bleeding heavily. Don't drive yourself: ask someone to take you, or call 999 if the pain means you can't move your leg to get there.
Get advice from NHS 111 now: you cannot move the knee or put any weight on it, or it is very painful, badly swollen or has changed shape, or it locks, gives way or clicks painfully. A pop, quick swelling and a knee that gives way point to an ACL injury: our ACL injury guide says what to do.

A turned ankle
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.
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.

Sleep problems: see a GP
- Changing your sleep habits hasn't helped, you've had trouble sleeping for months, or it's affecting your daily life in a way that makes it hard to cope.
- Your breathing stops and starts while you sleep, you make gasping, snorting or choking noises, or you always feel very tired in the day. If someone has seen it happen, it can help to bring them with you.

Driving when sleepy
Don't drive when you feel sleepy. With confirmed sleep apnoea and excessive sleepiness, you must not drive until it's under control.

Who should check first
The PAR-Q+ (Physical Activity Readiness Questionnaire for Everyone) asks about a heart condition or high blood pressure, chest pain, dizziness or losing consciousness, other long-term conditions and their medicines, a bone or joint problem that activity could make worse, and being told to exercise only under supervision. If you answer yes to any, check with your GP or a qualified exercise professional first. If you're over 45 and not used to hard exercise, ask a qualified exercise professional before the hardest sessions, and delay if you're ill.

Stop the session if
You feel any pain or become unwell, as the NHS advises for its Pilates videos, and especially for chest pain or pressure, unusual breathlessness, dizziness or fainting. If you have a health problem, an injury or any symptoms, get advice from a healthcare professional, such as a GP, before you start.
