Arm pain with chest pain or pressure
Call 999: arm pain that comes on suddenly with pressure, heaviness, tightness or squeezing across your chest, especially with shortness of breath, sweating or feeling sick. It could be a heart attack.
Call 999: shoulder or arm pain with chest pain that feels tight or squeezing, or chest pain that spreads to your arms, neck or jaw, especially with shortness of breath, sweating or feeling sick. It could be a heart attack.
Arm pain that comes on with exercise
Same day (NHS 111): your arm hurts when you exercise, but the pain goes away when you rest.
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.

A weak or numb arm with a drooping face
Call 999, even if it passes: sudden weakness or numbness in one arm, with a drooping face or slurred speech. These are signs of a stroke.
A pop at the front of the elbow
A sudden pop at the front of the elbow during a heavy pull, with bruising, a gap at the front of the elbow or a bulge in the upper arm, can be a torn biceps tendon. Go to an urgent treatment centre or A&E (in the US, urgent care or the emergency department), and don't wait for it to settle: repair is best done within the first 2 to 3 weeks.
Urgent treatment centre or A&E: a pop or snap and sudden pain during an effort, which could be a torn tendon. At the front of the elbow, with bruising and a bulge in the upper arm, don't wait for it to settle: a torn biceps tendon is best repaired within the first 2 to 3 weeks. If it happened weeks ago, still get it checked: repair is often still possible, though it may need a tendon graft.
A pop at the back of the elbow
Urgent treatment centre or A&E: a pop or snap at the back of the elbow during a push, a press or a dip, or after a fall onto an outstretched hand, then sudden pain and swelling, bruising at the back of the elbow or forearm, a gap above the point of the elbow, or weakness straightening the arm, especially overhead. Don't wait to see if it settles: a full tear in an active person is usually repaired, and expert guidance favours repairing it early.
Weakness straightening the arm that you notice without a clear injury, or back-of-elbow pain if you've had steroid injections near the elbow, have kidney disease or use anabolic steroids: get it checked. These can weaken the tendon.
A pop at the front of the armpit or chest
A pop or tearing at the front of the armpit or chest during a lift, followed by bruising into the chest or upper arm, a change in the shape of the chest or armpit, or weakness pushing, can be a torn chest tendon. Don't wait for it to settle: get help the same day from NHS 111 or an urgent treatment centre, as our pec strain guide explains.
An arm injury
Go to A&E or call 999 if you've injured your arm and it is numb, tingling or has pins and needles; a bone is sticking out or a bad cut is bleeding heavily; or the arm or elbow has changed colour or shape, or is at an odd angle. Don't drive yourself.
Urgent treatment centre or A&E: severe pain in your arm and it's difficult to move; you've injured your arm and heard a snap, or your arm has changed shape; or your arm tingles or feels numb.
A hot, swollen elbow
Same day (urgent GP appointment or NHS 111): a swollen elbow with a very high temperature, or you feel hot, cold or shivery; or severe pain in one joint that started suddenly, swelling around a joint, the skin around a joint has changed colour, or difficulty moving a joint. It could be an infection in the joint or the bursa, or gout.
Shoulder symptoms
Ask for an urgent GP appointment or get help from NHS 111 for sudden or very bad shoulder pain, an arm you can't move, a shoulder that has changed shape or is badly swollen, pins and needles that don't go away, no feeling in your arm or shoulder, an arm or shoulder that's hot or cold to touch, pain after an injury or a fall, severe pain in both shoulders, or feeling feverish or unwell. Go to A&E if, after an injury, you can't move your arm or your shoulder looks out of place or has changed shape. See a GP if shoulder pain is getting worse or hasn't improved after 2 weeks.
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.
Pins and needles or numbness
Pins and needles that keep coming back or are constant, numbness in the ring and little fingers that doesn't go, a weak or clumsy hand, or visible wasting between the thumb and index finger. Ask about referral: one NHS referral guide treats permanent numbness or wasting as urgent.
Arm weakness or numbness that keeps getting worse, severe pain that painkillers and rest do not touch, or an unexplained fever.
Stop and get checked if the arm feels weaker or numbness spreads.
A clot in the arm (our suggestion)
Our suggestion, from the NHS DVT page, which says DVT symptoms "can sometimes happen in your arm if that's where the blood clot is": for throbbing pain or swelling in one arm, red, blue or darkened skin around the painful area, or swollen veins, ask for an urgent GP appointment or get help from NHS 111, and call 999 or go to A&E if you also feel short of breath or have chest pain, as the NHS advises for DVT.

After big or unusual sessions
Same day (call NHS 111, or go to A&E if you feel very unwell): after a big or unusual session, such as hundreds of pull-ups, push-ups, dips or curls, a challenge or a new class, muscle pain, swelling or weakness far worse than the session explains, and dark pee (red, brown, tea or cola coloured), sometimes starting hours or days later. Dark pee isn't always there, so muscles far sorer, more swollen or weaker than the session explains still need the same-day check. It can be rhabdomyolysis, a breakdown of muscle that can harm the kidneys.
See a GP
Elbow or arm pain that hasn't gone after a few weeks of looking after it yourself (for tennis elbow, the NHS says after at least 2 weeks of self-care). In many areas you can refer yourself to NHS physiotherapy.
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.
Call 999 (911 in the US)
For chest pain that comes on suddenly and doesn't go away, feels tight or like squeezing, spreads to your arms, neck, jaw, stomach or back, or comes with sweating, feeling sick, light-headedness or breathlessness; arm pain that comes on suddenly with pressure, heaviness or squeezing across your chest; severe difficulty breathing, or a chest that feels tight or heavy; someone who faints while exercising; palpitations that don't go away, or come with chest pain, shortness of breath or feeling faint; or a headache that starts suddenly and is extremely painful, especially while lifting or straining. The NHS says a bleed on the brain may be more likely when lifting something heavy. Don't drive yourself to A&E.
Ask for an urgent GP appointment or call NHS 111
Ask for an urgent GP appointment or get help from NHS 111 for a headache that's triggered or made worse by coughing, sneezing, bending down or exercising. In the US, contact your doctor or urgent care.
During any session
Stop straight away if you feel any pain or become unwell, the NHS says, and contact 111 if your symptoms worry you or don't go away.
A dull ache in your muscles for a day or two after something new is normal. Joint pain that's sharp, gets worse during a set or lingers into the next day means switching to the easier option, and seeing a GP or physiotherapist if it carries on (our plans' rule). Our muscle soreness guide has more.
Check first
Speak to your GP first if you haven't exercised for some time or have medical conditions or concerns, as the NHS advises. Get advice before heavy lifting or hard straining work if your blood pressure is uncontrolled, or you have heart disease or chest pain when you're active, a pacemaker or defibrillator, diabetic eye disease, glaucoma, a hernia, recent eye or tummy surgery, or you're pregnant, as our breathing guide lists. After a recent shoulder dislocation or shoulder surgery, follow our shoulder dislocation guide or your surgical team first.
Speak to a GP first if you haven't exercised for some time, or if you have a medical condition or concerns. Get advice first, too, if you have a health problem, an injury or symptoms, have recently had a heart attack or an operation, or are pregnant or have recently given birth.
