What should you know about constant blocked nose?

Nasal congestion happens when the lining inside the nose swells, mucus becomes difficult to clear, or the passage is narrowed. Allergic rhinitis can cause blockage with sneezing, itching or watery discharge; house dust mite allergy may be worse in bedrooms. Chronic sinusitis can bring facial pressure, reduced smell and thick drainage. A common cold usually improves as the infection settles, so ongoing symptoms suggest another explanation. A deviated nasal septum, enlarged tissue or frequent exposure to smoke, dust, perfume or dry air can also contribute. Blockage may alternate sides, particularly as the normal nasal cycle changes.

Notice when the blockage appears and whether it follows cleaning, pets, bedding, work environments or sleep. Saline spray or a gentle saline rinse can loosen mucus; use sterile, distilled or previously boiled and cooled water for a rinse and keep the device clean. Reduce smoke and strong fragrances, and keep bedroom dust under control. A pharmacist or clinician can advise whether allergy medication is suitable. Decongestant nasal sprays should not be used longer than the product advice because overuse can worsen congestion. Arrange a routine review if the problem is persistent, affects sleep, or keeps returning.

Seek urgent medical help for severe breathing difficulty, swelling around an eye, vision changes, a severe headache with fever, confusion, or marked facial swelling. Arrange prompt assessment for one-sided blockage with repeated nosebleeds, bloody discharge, a new mass, or worsening facial pain. Otherwise, book a clinician visit when constant congestion continues despite sensible self-care, reduces your sense of smell, or causes loud snoring and unrefreshing sleep.

Ask whether your pattern fits Allergic Rhinitis, Chronic Sinusitis, or a structural nasal problem; whether an examination of the nose is needed; and which spray or rinse is appropriate for you. Mention medicines, allergies, snoring, reduced smell, nosebleeds and the settings that make symptoms better or worse.
