My one side nose remains always blocked, it alternates through out the day especially at night it becomes difficult to breath even from second open side. My ears also feel like it is blocked and head heavy. Not having cold problem. I am suffering from 4 months, consulted my family doctor, have taken so many medicines like cetrizine, peracetamol but no improvement. Plz advise whom should i consult.. Also advise if its safe to use Otrivin Daily for my nose problem?
