If bronchitis: it is probably viral, unless you are a smoker in which case it could be a secondary bacterial infection. Most of these cleaer up on their own, if you stop smoking, drink PLENTY of fluids and take something like Guaiafenesin to loosen up the phlegm and get it up and out. However, if you do not have a history of bronchitis it could be something else and you should probably be seen for a diagnosis.
