Long-term nasal pain and itching are commonly due to Allergic rhinitis or chronic irritation of the nasal lining. Try to avoid dust, smoke, and strong smells, use saline nasal spray or steam inhalation for relief, and an antihistamine like Cetirizine may help reduce symptoms. Avoid picking or scratching the nose, as it worsens irritation. If symptoms persist for a year, it?s best to see an ENT specialist for proper evaluation and long-term treatment.
