What should you know about continuous blocked nose?

Nasal blockage happens when the lining becomes swollen, mucus thickens, or the passage is narrowed. Allergic rhinitis may cause sneezing, itching and watery discharge, while house dust mite allergy can produce symptoms that are worse indoors or during sleep. Sinusitis or chronic sinusitis may add facial pressure, reduced smell and coloured mucus. A common cold generally brings a changing group of upper-airway symptoms. Night-time blockage with loud snoring, pauses in breathing or morning tiredness should raise the possibility of obstructive sleep apnoea.

Notice whether symptoms follow dust, pets, outdoor air, temperature changes or a recent infection. Saline nasal rinsing may loosen mucus; use safe water and clean equipment as directed. Keep rooms ventilated, reduce known irritants and drink enough fluid. A pharmacist or clinician can explain whether allergy medication is suitable and how to use a nasal spray correctly. Do not use decongestant sprays for longer than the product instructions, because overuse can worsen congestion. Arrange an examination if blockage persists or affects sleep.

Book an appointment for ongoing one-sided blockage, repeated sinus symptoms, reduced smell that does not recover, recurrent nosebleeds, facial swelling or symptoms that disturb sleep. Seek urgent help for difficulty breathing, swelling around an eye, severe headache with fever, confusion, or rapidly worsening illness. A clinician may inspect the nose, review medicines and allergies, and decide whether further testing is needed.

Ask what pattern best fits your symptoms, whether allergy testing or a nasal examination is needed, how long to use any spray, and whether snoring or witnessed pauses in breathing should be assessed.
