Please help. My husband suffers from terrible post nasal drip that causes him to cough violently. No help from ENT doc, just rx for cough pills. Help!

? Sinusitis. Can cause those symptoms, also possibility of lower airway irritation secondary to post nasal discharge, let him see his doctor or urgent care and mention that he has? Chronic sinusitis or chronic sinus disease, a limited coronal CT study of his sinuses would readily show whether he has the disease, and antibiotics then would be needed, later he needs to see an allergist for evaluation, take care.
