    Acute bronchitis, or chest cold, is a condition that occurs when the bronchial tubes in the lungs become inflamed. The bronchial tubes swell and produce mucus, which causes a person to cough.

    This often occurs after an upper respiratory infection like a cold. Most symptoms of acute bronchitis (chest pain, shortness of breath, etc.) last for up to 2 weeks, but the cough can last for up to 8 weeks in some people.
