What are the signs and symptoms of pneumothorax?
Symptoms of a pneumothorax include chest pain that usually has a sudden onset. The pain is sharp and may lead to feelings of tightness in the chest. Shortness of breath, rapid heart rate, rapid breathing, cough, and fatigue are other symptoms of pneumothorax. The skin may develop a bluish color (termed cyanosis) due to decreases in blood oxygen levels.
