What should you know about unblock blocked nose?

Nasal blockage happens when the lining inside the nose swells or becomes coated with mucus. A common cold may cause a short-lived blocked nose. Allergic rhinitis can bring sneezing, an itchy nose, and watery discharge, while sinusitis may add facial pressure or thick mucus. Repeated blockage, especially with snoring or disturbed breathing during sleep, deserves assessment because chronic sinusitis or obstructive sleep apnoea may need targeted care.

Try a saline nasal spray or rinse using a product prepared for nasal use, and follow its instructions carefully. Drink regularly, rest, and avoid cigarette smoke, strong scents, and dusty air. A humid environment may feel more comfortable, but avoid very hot steam that can burn the skin. Allergy medication may help when symptoms follow a clear trigger; a pharmacist can check which option fits your age, pregnancy status, and other medicines. Do not use decongestant sprays for longer than the label advises, because overuse can worsen blockage.

Arrange a medical review if blockage is persistent, repeatedly affects one side, or interferes with sleep, eating, or daily activity. Seek urgent help for difficulty breathing, swelling around the eyes, severe facial pain, confusion, or a severe headache with a stiff neck. Get prompt advice if symptoms follow a facial injury, or if a child is struggling to breathe or drink.

Ask whether the pattern fits an infection or allergy, whether nasal rinsing is appropriate, how long a spray should be used, and whether snoring or night-time pauses in breathing warrant a sleep assessment.
