Bronchitis is an inflammation of the main air passages (bronchi) to your lungs. It causes a cough, shortness of breath and chest tightness. Coughing often brings up yellow or greenish mucus. There are two main types of bronchitis: acute and chronic.
Acute bronchitis is often caused by the same viruses that cause colds. It usually starts as a sore throat, runny nose or sinus infection, then spreads to your airways. It can cause a lingering dry cough, but it usually goes away on its own.
