Been coughing for weeks...?

reoccuring bronchitis can be a result of a lot of different things. One being lung cancer. But that would have to be years of it reoccuring. So obvouisly when you can see a docotor agian do so. Sugary foods and fried foods are bad, Caffine can also make a difference, more so in how you feel though, then in how you are breathing. I would try to avoid it.
