See doctor: There are many potential causes for your problem but asthma and/or allergic rhinitis (hay fever) with or without sinus infection would be the 3 most likely ones. If you are a smoker, stop it immediately. If you are not, consider seeing an allergist. A lung function test is a must. Do note that most cases of chronic cough are caused by more than a single disease entity.
