Hello! Your problem could be chronic sinusitis leading to a post nasal drip and throat irritation with cough. You will need a diagnostic nasal endoscopy and a ct scan of the nose and paranasal sinuses to evaluate for it. Please stop using otrivin or nasivion or any such drops as they lead to rebound congestion if used for long durations. A topical steroid nasal spray can be useful.
