No, acute bronchitis does not come back every year, but usually lasts for 2-3 weeks. However, if symptoms persist longer than 3-4 weeks, you may be classified as having chronic bronchitis, which can return for multiple years in a row. Bronchitis can result from a cold or flu virus, or exposure to substances that irritate the lungs (e.g., pollution, smoke). It is this long-term irritation of the lungs that may lead to developing chronic bronchitis. Symptoms include: - Wheezing - Shortness of breath - Chest tightness or discomfort - Fatigue - Coughing up mucus  If you suspect that you may have bronchitis, be sure to get plenty of rest and drink lots of fluids. Over-the-counter pain relievers can also help relieve aches and pains (e.g., Tylenol, DayQuil/NyQuil). Lastly, using a humidifier will also help expand the inflamed airways and expel mucus. Be sure to follow all instructions on any medication you consume and notify your doctor of any questions or concerns you may have.
