Where it hurts is a clue, not a diagnosisStrong evidence
The NHS chest pain page says a chest sprain or strain starts after a chest injury or chest exercise, may get worse when you breathe in and feels better when you rest the muscle, and that most chest pain isn't the heart (a page past its review date). A review says pain you can reproduce by pressing, no history of heart disease, pain that isn't behind the breastbone or heavy and pressing, well-localised pain and stabbing pain all make chest wall pain more likely, but pain reproduced by pressing doesn't prove it.
So this guide says a spot points to a cause rather than proving it, and chest pain without an injury needs checking.

After a fall, a blow or a coughing fit: a bruised or broken ribStrong evidence
The NHS says broken or bruised ribs usually follow a fall, a blow to the chest or severe coughing, with strong pain when you breathe in or cough, swelling or tenderness, sometimes bruising, and a crack you felt or heard if a rib is broken. There's often no need for an X-ray, because ribs can't easily be splinted or supported and are left to heal. An emergency department leaflet says it doesn't routinely X-ray rib fractures because the X-ray wouldn't change the treatment, and that rib injuries can hurt for 3 to 6 weeks.

Older age makes a rib injury more seriousEmerging evidence
In 277 trauma patients aged 65 and over with broken ribs, pneumonia occurred in 31% against 17% of younger adults with similar injuries, and each extra broken rib raised the risk of pneumonia by 27% and of death by 19%. These were hospital patients with significant injuries, but they are why older people, and anyone with heart or lung disease, should get a rib injury checked.

Beside the breastbone: costochondritis and Tietze syndromeStrong evidence
Costochondritis is inflammation where the ribs join the breastbone: sharp pain at the front or side of the chest, worse moving your upper body, lying down, breathing deeply or pressing on it, the NHS says, linked to chest injuries, repetitive upper-body movements such as lifting, a lot of coughing and infections. A review says it is commonest at 40 to 50, slightly more in women, and accounts for 6% to 13% of chest pain seen in general practice, usually at the second to fifth rib joints, without swelling.
Tietze syndrome is rarer: a visible, tender swelling, usually at one joint by the second or third rib, most often under 40.

Pressing on the pain doesn't rule out the heartStrong evidence
A clinical review says coronary artery disease was present in 3% to 6% of adults with chest pain whose chest wall was tender, and advises an electrocardiogram (ECG) for anyone over 35, at risk of heart disease or with heart or lung symptoms. A second review says most people with chest pain still need a thorough check, including an ECG at least. The NHS says get help from NHS 111 if you think you have costochondritis, so the chest pain can be checked.

Muscles: between the ribs and at the sideEmerging evidence
A review of chest wall problems in athletes says the muscles between the ribs (the intercostals) can be strained, causing tenderness between the ribs. Side strains, tears of a trunk muscle at the lower ribs, are common in fast bowlers: in 57 first-class bowlers, return to play took a mean of 39 days, 44% took more than 6 weeks, and a muscle tear on a magnetic resonance imaging (MRI) scan made more than 6 weeks 8 times more likely. No study has tested treatments for an intercostal strain.

Rib stress fracturesEmerging evidence
Rib stress fractures build up with repeated loading rather than one injury. A review found them in 8.1% to 16.4% of elite rowers over a career, mostly in the fourth to eighth ribs at the side of the chest, and golf and baseball pitching are other causes. Rib pain with no injury that builds with training needs a GP.

Slipping rib syndromeEmerging evidence
In slipping rib syndrome, one of the lower ribs (the 8th to 10th) moves too much at the front, causing pain at the lower edge of the rib cage that comes and goes with posture or movement, sometimes with a click. It is rare and easily missed. A review says the story and an examination usually confirm it, with an ultrasound scan done while you move as a help, and a review of athletes describes a hooking test that reproduces the pain.

ShinglesStrong evidence
Shingles starts with a tingling or painful feeling in an area of skin, then a rash, usually on the chest and tummy, on one side of the body. The NHS says it can rarely cause pain without a rash, and to see a pharmacist within 3 days of the rash appearing.

The lungs, the heart's lining and the gallbladderStrong evidence
Pleurisy, inflammation of the lining of the lungs, causes sharp chest pain when you breathe in, worse coughing, sneezing or moving. A clot in the lungs (pulmonary embolism) causes sudden difficulty breathing and chest pain that is worse breathing in. Asthma + Lung UK says a collapsed lung causes a sudden, sharp, stabbing pain in the chest or shoulder and breathlessness, and is more common at 15 to 34, in people who smoke and in tall, thin people. Pneumonia brings a cough, breathlessness and chest pain.
Pericarditis, inflammation of the sac around the heart, causes sharp, stabbing chest pain that is worse lying down and better leaning forward (an NHS page past its review date). Gallstone pain lasts more than 30 minutes, in the middle of the tummy or just under the ribs on the right.

PregnancyEmerging evidence
An NHS trust's maternity physiotherapy leaflet (past its review date) says rib pain is common later in pregnancy, usually on one side just under the breast or on the side of the chest, from the growing womb, hormones, the baby's movements, breast growth and heartburn, and that most of it isn't serious. The NHS lists pain below the ribs among the symptoms of pre-eclampsia, which need checking urgently, and asks you to contact your GP or midwife urgently about back pain with pain in one or both sides under the ribs.

Rarer causesStrong evidence
Myeloma, a blood cancer, can cause bone pain in the back, hips, shoulders or ribs, with tiredness, thirst and weight loss. Lung cancer can cause chest or shoulder pain with a cough that won't go away. Bone pain that is constant or worse at night needs a GP.

When a scan or test helpsStrong evidence
A bruised or broken rib often needs no X-ray, because it wouldn't change the treatment; scans are for a serious accident or a suspected lung injury. Chest pain without an injury needs an ECG for anyone over 35, at risk of heart disease or with heart or lung symptoms, and sometimes a chest X-ray; costochondritis is a diagnosis made once other causes have been considered, and no test confirms it.
Slipping rib syndrome is usually confirmed by the story and an examination, with an ultrasound as a help. Pleurisy may need a chest X-ray, blood tests, an ultrasound or a computed tomography (CT) scan, and a suspected clot or collapsed lung is checked in hospital.

How it usually goesEmerging evidence
Bruised or broken ribs usually get better within 2 to 6 weeks, the NHS says, and NHS trust leaflets give about 4 to 6 weeks for a broken rib to heal, with some discomfort after that; contact a GP if a broken rib is no better after 6 to 8 weeks. Costochondritis can last a few weeks to several months, and a review says most people recover with simple care.
Side strains in fast bowlers took a mean of 39 days. The shingles rash heals in up to 4 weeks, though the skin can stay painful for weeks, and pleurisy often settles in a few days. No one can promise a date.
