Unlikely: A cough of this duration requires a doctor to listen to your lungs and to take an x- ray to rule out a tissue mass in the lungs.

Not viral: Viral illnesses resolve in 10-14 days so lingering cough could be bacterial subacute sinusitis, residual post nasal drip or airway inflammation. If bacterial Amoxicillin a good first choice. If cough persists then see md. Unlikely to develop resistance with infrequent antibiotic usage.
