No study has counted the causesEmerging evidence
No study we found has counted the causes of upper back pain that hurts when you breathe, so the order on this page comes from guidelines and reviews of chest pain. In emergency departments, a clot in the lung was found in 5% to 21% of people with sharp chest pain on breathing, a review says, and in 21% of 173 people in one study. In general practice, the chest wall causes a quarter to a half of chest pain (24.5% to 49.8% across 6 lower-risk studies of about 3,900 people), and in 1,212 German patients aged 35 or over, GPs judged 46.6% to come from the chest wall.
Upper and mid back pain is common on its own: across 33 studies of the general population, 3.5% to 34.8% of people had it in a year. Those studies weren't about pain on breathing, so they don't tell you what your pain is; the warning signs do.

The lungs and the lining of the chestStrong evidence
Pleurisy, inflammation of the lining of the lungs, causes sharp chest pain when you breathe in that is worse when you cough, sneeze or move, and it may spread to your shoulders and back, the NHS says. Pneumonia causes a cough, often with yellow or green phlegm, a high temperature, breathlessness, and chest pain when breathing or coughing.
A clot in the lungs (pulmonary embolism) causes sudden breathlessness, chest or upper back pain that can be worse when you breathe in, a fast heartbeat and sometimes coughing up blood, and in a large study its symptoms could be mild or even absent with a big clot. A collapsed lung (pneumothorax) causes a sudden, sharp, stabbing pain in the chest or shoulder that is worse when you breathe in, with breathlessness; it is commonest at 15 to 34, in people who smoke and in tall, thin people.

The heart, and a tearing painStrong evidence
Heart attack pain can feel tight, heavy or squeezing and spread to the arms, neck, jaw or back; the NHS chest pain page names the back, and the British Heart Foundation says women may feel it spreading to the upper back. Pericarditis, inflammation of the lining round the heart, causes sharp or stabbing chest pain that is worse breathing in, swallowing, coughing or lying down and better sitting up or leaning forward, often after a viral infection. Sudden chest or back pain that feels like something being torn inside, with breathlessness and problems walking, seeing or speaking, is a 999 call, the NHS says.

The muscles, the rib joints and the ribsEmerging evidence
A sprain or strain of the chest wall starts after an injury or exercise, may get worse when you breathe in, and feels better when you rest the muscle, the NHS says. When the small joints where the ribs meet the spine were injected in 8 healthy volunteers, they gave a deep, dull ache and pressure over the joint itself, without chest wall pain. No study we found has measured how often these joints or muscles cause pain on breathing.
A fall, a blow or severe coughing can bruise or break a rib, and with thin bones (osteoporosis) a cough or sneeze can be enough. In 54 people with ribs broken by coughing, 78% were women, 85% had coughed for 3 weeks or more, the first chest X-ray showed the break in only 58%, and 65% of the 26 who had a bone scan had low bone density; in another 90 people, 64% had been through the menopause and most breaks were in ribs 4 to 9. Rowers can develop rib stress injuries from repeated loading, and costochondritis causes pain beside the breastbone at the front.

Bone, inflammation and other causesStrong evidence
With osteoporosis, a cough or sneeze can break a rib or partly collapse a bone in the spine. Ankylosing spondylitis can affect the joints where the ribs meet the spine and breastbone, causing chest pain and making it hard to expand the chest when you breathe deeply. Myeloma can cause bone pain in the back or ribs, and in people with cancer, back pain that is worse when coughing or sneezing, or at night, can mean the cancer has spread to the spine, NICE says.
Shingles can start as a tingling or painful band on one side of the back or chest before the rash appears. Gallstones cause pain just under the right ribs or in the middle of the tummy, and pain spreading from the tummy to the back with being sick is a 999 call.

How to tell them apartEmerging evidence
How it started is a clue: most of the dangerous causes (a clot, a heart attack, a tear in the main artery and a collapsed lung) come on over minutes, while infections, cancer and inflammation develop over hours to weeks, a review says. True breathlessness points to a clot, a collapsed lung or pneumonia; holding your breath because breathing hurts is different. A fever with a cough and phlegm points to pneumonia or pleurisy. A painful, swollen leg, a recent operation, a long journey, pregnancy or having had a baby in the last 6 weeks raise the chance of a clot.
Pain that is worse lying back and better leaning forward suggests pericarditis, and a burning band on one side suggests shingles. Pain you can press on is typical of the chest wall but doesn't rule out the heart: in an emergency department, 6% of people with costochondritis were having a heart attack, against 28% of people with other chest pain.

When a test or scan helpsEmerging evidence
The warning signs decide whether you need hospital tests: an electrocardiogram (ECG) and blood tests for the heart, a score, a blood test and a scan for a suspected clot, and a chest X-ray for suspected pneumonia in hospital. For a bruised or broken rib there's often no need for an X-ray, the NHS says, and NHS inform says most rib or chest injuries don't need one; X-rays missed 4 in 10 ribs broken by coughing in one series. Pleurisy may need blood tests, a chest X-ray, an ultrasound or a computerised tomography (CT) scan. The NHS asks you to see a GP for back pain at the top of the back, between the shoulders.

How it usually goesEmerging evidence
Bruised or broken ribs usually get better by themselves within 2 to 6 weeks, the NHS says, and NHS inform says most of the healing after a chest or rib injury happens within 6 to 8 weeks. Pleurisy usually gets better on its own in a few days, the NHS says, though it can sometimes be a sign of something more serious, such as pneumonia. Most people feel better from pneumonia in 2 to 4 weeks, and NICE expects chest pain to have substantially eased by 4 weeks and most symptoms by 3 months. Chest wall pain can linger: 55.4% of people in general practice still had chest pain 6 months later. No one can promise a timescale.
