What should you know about one nostril always blocked?

The nasal lining naturally swells on alternating sides during the nasal cycle, so mild side-to-side change can be normal. A blockage that remains on the same side may instead relate to a bent septum, enlarged tissue, nasal polyp, trapped mucus, or a local growth. Allergic Rhinitis can cause congestion, sneezing and watery discharge, while Sinusitis or Chronic Sinusitis may add facial pressure, reduced smell or thick mucus. A Common Cold usually improves as the infection settles. House Dust Mite Allergy can keep symptoms going indoors.

Use saline spray or a gentle saline rinse with safe, clean water, and avoid smoke, strong scents and nose-picking. Keep a note of which side is blocked, whether symptoms vary with position, and any discharge, bleeding or reduced smell. Allergy Medication may help when itching, sneezing and watery symptoms point to allergy; use medicines according to their label or a clinician's advice. Do not use decongestant nasal sprays for longer than directed, because overuse can worsen congestion. Arrange a routine examination if the same side stays blocked or affects sleep.

Seek prompt medical care for repeated one-sided nosebleeds, bloody or foul-smelling discharge, severe facial pain, swelling around the eye, fever with worsening symptoms, or changes in vision. Get urgent help for trouble breathing, marked facial swelling, confusion or a severe headache. A clinician can inspect the nasal passage and decide whether further testing or an ear, nose and throat referral is needed.

Could a septum or swollen nasal tissue explain the fixed-sided blockage? Do my discharge, smell changes or nosebleeds suggest infection or another local cause? Which spray or rinse is suitable for me, and how long should I use it?
