Lung Inflammation Symptoms: What to Watch For

A cough is a common indicative of lung inflammation. When the lungs are inflamed, they produce more mucus than usual. This mucus can irritate the airways and cause coughing. Coughing is a natural reflex that helps to clear the airways of mucus and other irritants. In some cases, a cough may be a sign of a more serious medical condition, such as pneumonia or bronchitis.
