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. The American Heart Association says these need immediate medical evaluation.

Call 999 (911 in the US)
For chest pain that comes on suddenly and doesn't go away, feels tight or like squeezing, or spreads to your arms, neck, jaw, stomach or back; shoulder or arm pain with chest pain; a sudden, extremely painful headache, for example during a heavy lift; someone who faints while exercising; palpitations that don't go away, or come with chest pain, breathlessness or feeling faint; or signs of a stroke, even if they've stopped. Don't drive yourself to A&E.

Check before you start
If you haven't exercised for some time or have a medical condition, speak to your GP first, as the NHS advises. Get advice before heavy lifting 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.

A shoulder out of place
Call 999 or go to A&E if, after a fall or injury, or after your shoulder slipped during a press, your shoulder looks out of place or has changed shape, or you can't move your arm. Don't drive yourself, and don't try to put it back in.

A sudden shoulder problem
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 badly swollen or misshapen shoulder; pins and needles that don't go away; no feeling in the arm; an arm that's hot or cold to the touch; pain after an injury; or severe pain in both shoulders.

A pop at the front of the shoulder, chest or upper arm
Get help the same day from NHS 111 or an urgent treatment centre for a pop or tearing at the front of the armpit or chest during a lift, then bruising into the chest or upper arm, a change in the shape of your chest or armpit, or weakness pushing: it can be a torn pec tendon, and repairs done within about 6 weeks did better than later ones. A sudden pop or snap with pain at the shoulder or upper arm, with or without a bulge low in the upper arm, needs a GP or NHS 111 the same day. The NHS says to get help from NHS 111 if you think you've ruptured a tendon.

Shoulder pain that doesn't settle
See a GP or physiotherapist if pain is getting worse or hasn't improved after 2 weeks of looking after it yourself, or it's very hard to move your arm, or if your shoulder has partly or fully come out of joint, or you worry it might. In many areas you can refer yourself to physiotherapy.

A new lump or bulge
See a GP if you think you have a hernia, and get help from NHS 111 if a hernia becomes painful or you feel sick. Call 999 or go to A&E for a femoral hernia (a lump at the top of the thigh) with very bad tummy pain, sickness, being unable to fart or poo, a high temperature or sudden confusion.
