Traumatic Pneumothorax
Symptoms of Traumatic Pneumothorax
People have chest pain. Most of the pain is due to the injury that caused the pneumothorax. They may feel short of breath or breathe rapidly and feel that their heart is racing, particularly if the amount of air is large. If air accumulates under the skin, the skin feels crackly and makes a crackling sound when touched. Sometimes air from a collapsed lung accumulates under the skin of the chest or neck, and the skin feels crackly when touched.
