Hello! Your problem could be chronic sinusitis leading to a post nasal drip and throat irritation. This could be the reason for your persistent cough. A diagnostic nasal endoscopy will help to confirm the diagnosis. Antihistamines like levocetrizine and a topical steroid nasal spray like fluticasone preparations can be useful along with a cough suppressant temporarily.
