I have had a cough now for over 2 months that just does not seem to go away, ive been to the doctor twice concerning it and he thinks its a bacterial infection, the first time he prescribed biaxin xl and that helped to ease the cough but once the prescription ended the cough seemed to start coming back and after another 3 weeks of the cough coming back i went to see him again and he prescribed avexol and now the prescription for that just ended and the cough hasnt gone away, im really starting to worry as to what it might be
By convention in Medicine, chronic cough is a cough that lasts 3 months or more. Not to quibble, but in my opinion your cough of over 2 months definitely falls into that category. There are many causes of chronic cough. The most common may be those that follow respiratory infection, especially in persons who have COPD/Emphysema or asthma. Of the non-infectious causes, post-nasal drip (often allergic), acid reflux and asthma are probably the most common causes.
You might wish to ask your doctor why he believes the cause of your cough to be infectious and, given the duration of over two months, what kind of bacterial infection it might be.
At this point the most important thing would be to rule out the more serious causes of persistent cough and this would include a great variety of diseases of the respiratory tract from the sinuses on down and into the lungs. If you are raising mucous, it should be examined for infection and, if you are a smoker, for malignant cells. You should also of course have a chest X-ray. Should none of this testing be revealing, it would be wise for you and your doctor to seek consultation with a lung specialist (pulmonologist).
The cough you have experienced must not be ignored. The most important thing is that you and your doctor continue a diagnostic evaluation that might also include bronchoscopy until the cause of your cough is determined with reasonable certainty.
