What should you know about flank pain when breathing?

The muscles between the ribs and the lining around the lungs move with each breath, so irritation after coughing, exercise, or an injury can hurt more during deep breathing. Pain from the urinary tract may be less tied to breathing and more likely to occur with urinary changes, fever, or nausea. [Kidney Stones](/conditions/kidney-stones/) and [Kidney Infection](/conditions/kidney-infection/) can both cause flank pain, while a [Urinary Tract Infection](/conditions/urinary-tract-infection/) may cause burning or frequent urination. The location can overlap with chest or upper-abdominal pain, so the whole symptom pattern matters.

Notice whether the pain follows a cough, movement, deep breath, or injury, and record fever, breathlessness, chest discomfort, dizziness, and urine changes. Avoid strenuous activity until the cause is clearer. Arrange medical advice for new pain that persists, limits breathing, follows an injury, or occurs with fever or urinary symptoms. A clinician may examine your chest, back, and abdomen and decide whether tests are needed.

Call emergency services for severe breathing difficulty, blue or grey lips, fainting, new confusion, crushing chest pain, or coughing blood. Seek urgent medical assessment for sudden severe pain, a rapid worsening, high fever, or breathlessness with one-sided leg swelling. Do not drive yourself if you feel faint or severely short of breath.

Could this be from the chest wall, lungs, muscles, or urinary system? What examination or tests are appropriate? Which breathing or chest symptoms should prompt emergency help? How can I stay comfortable without hiding a worsening symptom?
