Teen's lungs collapse after screaming in a concert: Report
US-based doctors have reported a case of a 16-year-old girl, who complained of shortness of breath after "forceful screaming" during a concert. An X-ray confirmed that air was trapped behind the pharynx and in the chest cavity. Further examination revealed another symptom called subcutaneous crepitus, where a crackling sound was produced under the skin upon pressing the neck and chest.
