What should you know about recurring blocked nose?

Allergic rhinitis may cause congestion with sneezing, itching, or watery eyes, while house dust mite allergy can produce symptoms around bedding or indoor spaces. Chronic sinusitis may add facial pressure, reduced smell, or thick drainage. Colds usually improve, but repeated infections or persistent inflammation need assessment. Night-time blockage, loud snoring, pauses in breathing, or morning tiredness can point toward obstructive sleep apnoea. A blockage that stays mainly on one side also warrants examination.

Track when blockage appears, whether it changes sides, and links with dust, pets, seasons, illness, or sleep. Saline nasal rinsing may loosen mucus; use safe water and clean equipment. Reduce known irritants and follow label directions for any medicine. Decongestant sprays used too often can make congestion rebound, so ask a pharmacist or clinician about a suitable plan. Allergy medication may help when an allergic pattern is present.

Book a medical review for blockage that keeps returning, disrupts sleep, reduces smell, or comes with recurrent facial pain or discharge. Seek urgent care for swelling around the eye, severe headache, high fever, stiff neck, vision change, or breathing difficulty. Arrange prompt assessment for a persistent one-sided obstruction, repeated nosebleeds, or a new lump.

Do my symptoms fit allergic rhinitis, chronic sinusitis, or another cause? Should I be checked for sleep apnoea? Which saline, allergy, or nasal treatments are appropriate, and how long should I use them?
