See doctor...: If you have a cough that is persisting for a few weeks or longer, see your doctor for diagnosis and treatment. If the cough is non-productive, possibilities include bronchospasm from any cause, gerd, post-nasal drip or a combination of factors. If you have a persistent productive cough, it could be chronic bronchitis, a form of copd, especially if you have a smoking history.
