Lung disorders that can cause chest pain include:
- Pulmonary embolism. This cause of chest pain occurs when a blood clot becomes lodged in a lung (pulmonary) artery, blocking blood flow to lung tissue.
- Pleurisy. This is when the membrane that covers the lungs becomes inflamed. Pleurisy can cause chest pain that's made worse with inhaling or coughing.
- Collapsed lung. A collapsed lung occurs when air leaks into the space between the lung and the ribs. The chest pain associated with a collapsed lung typically begins suddenly and can last for hours.
- Pulmonary hypertension. High blood pressure in the arteries carrying blood to the lungs (pulmonary hypertension) also can produce chest pain.
