What are the symptoms of a collapsed lung?

Shortness of breath: Shortness of breath and pain are the most common symptoms. This requires urgent evaluation.

Short of breath/Pain: The most common symptoms are acute onset of chest pain and shortness of breath. If this were to occur you should seek immediate medical attention and have a chest x-ray to diagnose the problem.

Short of breath: Estimated at least 10% spontaneous pneumothorax are asymptomatic. Symptoms if present may include shortness off breath, cough, and/or chest pain. The first line of diagnosis for large pneumothorax is a good history and physical examination (stethoscope). Most smaller pneumothoraces can be diagnosed with good 2 view chest x-ray series. Occasionally, a ct-scan may be necessary.
