What should you know about a fully blocked nose?

A blocked nose can occur when blood vessels and tissues inside the nose swell. A Common Cold often brings congestion with sneezing, a sore throat or cough. Allergic Rhinitis may cause repeated blockage, itching and watery eyes, while House Dust Mite Allergy can produce symptoms indoors or on waking. Sinusitis may add facial pressure, reduced smell or thick nasal discharge; Chronic Sinusitis describes symptoms that continue or recur over a longer period.

Night-time blockage with loud snoring, pauses in breathing or morning headaches can be associated with Obstructive Sleep Apnoea. One-sided blockage, bleeding or a reduced sense of smell should be mentioned to a clinician rather than assumed to be a simple cold.

Drink fluids, rest and consider saline spray or a gentle saline rinse made with safe water. Avoid smoke and other irritants. If allergies are suspected, reduce dust exposure and wash bedding regularly. Allergy Medication may help some people, but ask a pharmacist or clinician which option fits your symptoms and how long to use it. Use decongestant sprays only as directed, because prolonged use can worsen congestion.

Seek urgent help for difficulty breathing, swelling of the face or throat, severe headache with fever, confusion, an eye that is swollen or painful, or symptoms after a significant injury. Arrange medical review for severe facial pain, persistent fever, repeated nosebleeds, one-sided blockage, symptoms that keep returning or congestion that is not improving. Children who struggle to breathe or drink need prompt attention.

Does the pattern suggest allergy, infection or another cause? Is a nasal examination needed? Which saline or allergy treatment is suitable? Could my night symptoms suggest sleep apnoea? How long should I wait before arranging a review?
