What causes chest pain? Chest pain can be caused by a range of conditions, from not serious to life-threatening. It may be caused by a heart attack or a blood clot in your lungs. Sometimes chest pain or pressure is caused by poor blood flow to your heart (angina). Infection, inflammation, or a fracture in the bones or cartilage in your chest can cause pain or discomfort. Chest pain can also be a symptom of a digestive problem, such as acid reflux or a stomach ulcer.
