SymptomsBy Mayo Clinic staff
Signs and symptoms of a pneumothorax usually include:
- Chest pain. Sudden, sharp chest pain on the same side as the affected lung — this pain doesn't occur in the center of your chest under the breast bone. And it doesn't worsen when you breathe in and out.
- Shortness of breath. This may be mild or severe, depending on how much of your lung is collapsed and whether you have underlying lung disease.
When to see a doctor
See your doctor right away if you have sudden chest pain and trouble breathing. Many conditions other than pneumothorax can cause these symptoms, and most require an accurate diagnosis and prompt treatment. If your chest pain is severe or breathing becomes increasingly difficult, get immediate emergency care.
