Blocked nose for months: what to know

Long-lasting congestion can reflect allergic rhinitis, chronic sinusitis, enlarged nasal tissues, a deviated septum, or irritation from smoke and dust. Repeated use of medicated decongestant spray can also keep the lining swollen. Allergy-related blockage may fluctuate with exposure and accompany sneezing or itchy eyes; sinus disease may involve pressure, reduced smell, or nasal discharge. These patterns guide an examination but do not replace one.

Arrange a primary-care appointment and record when symptoms began, whether one or both sides are blocked, triggers, sleep effects, smell changes, and every nasal or oral medicine used. Saline spray or a safe saline rinse may clear mucus. Reduce exposure to smoke, dust, and strong fragrances. If allergy features are present, ask a pharmacist about Allergy Medication rather than starting several products together.

Get prompt medical advice for persistent one-sided blockage, recurrent nosebleeds, bloody discharge, worsening facial pain, swelling around the eye, or a new change in vision. Seek emergency help for severe breathing difficulty, confusion, fainting, or rapidly worsening swelling. Sleep disruption, loud snoring, or pauses noticed during sleep should also be discussed because nasal obstruction can compound sleep problems.

Could allergy or sinus disease explain this pattern? Do I need a nasal examination or referral? Which treatment is appropriate, and could any spray be causing rebound blockage?
