Cough and...: Your symptoms sound like chronic bronchitis. You may need more than antibiotics. See your doctor, get a cultures of your sputum, and some testing to show the functions of your lungs. A lung specialist may be needed to further diagnosis and treatment your problem. Please stop smoking as soon as possible, if you have not already.

Chronic bronchitis : Chronic bronchitis is a form of COPD and it is due to airway inflammation usually related to cigarette smoking. Symptoms include productive cough and shortness of breath w/o symptoms of infection. It is not due to infection so antibiotics are ineffective. Treatment consists of smoking cessation, bronchodilator and often steroid inhalers. See your doctor for diagnosis/treatment. There is no cure.
