How to stop a blocked nose

A blocked nose occurs when the lining inside the nose swells or mucus narrows the airflow. A common cold often brings congestion with a runny nose and sore throat. Allergic rhinitis can cause sneezing, itching, and watery eyes, while house dust mite allergy may cause symptoms indoors or on waking. Sinusitis can add facial pressure, reduced smell, or thick discharge. Ongoing congestion may be chronic sinusitis. Night-time blockage and loud snoring can also be linked with obstructive sleep apnoea.

Use a ready-made saline spray or a properly prepared saline rinse according to its instructions. Breathe in warm, moist air without placing your face close to hot water. Rest, drink regularly, and avoid smoke and other irritants. If allergies are likely, reduce exposure to the trigger and ask a pharmacist about allergy medication. Decongestant sprays should be used only as directed and for the recommended short period, because overuse can worsen blockage. Check suitability if you are pregnant or have another health condition.

Seek urgent care for difficulty breathing, swelling around the eyes, severe headache with fever, confusion, or a stiff neck. Arrange review for one-sided blockage with bleeding, severe facial pain, reduced vision, repeated nosebleeds, symptoms that persist, or congestion that regularly disrupts sleep. A clinician can check the nose and identify whether allergy, sinus disease, or another problem is involved.

Ask whether your pattern fits a common cold, allergic rhinitis, sinusitis, chronic sinusitis, or sleep-related breathing difficulty. Discuss which spray or allergy medication is suitable and how long to use it.
