Blocked nose: what to do

A stuffy nose is a symptom rather than a diagnosis. Viral infections often cause congestion alongside cough, sore throat, or tiredness. Allergies may cause itching and sneezing, especially after exposure to a trigger. Sinusitis can cause facial pressure, reduced smell, or discoloured mucus. Dry air, smoke, and irritants can swell the nasal lining too. These patterns can overlap, so a blocked nose is not proof of any particular condition.

Use a saline spray or rinse exactly as directed, with a clean device and the recommended water preparation. Blow your nose gently rather than forcefully. Drink fluids, rest, and consider a comfortably humid environment if dry air irritates you. Keep smoke and strong scents away from the room, and wash bedding regularly if dust is a trigger. A pharmacist can help you choose an appropriate product; mention pregnancy, long-term conditions, and regular medicines before using a decongestant or allergy medication.

Get urgent help for severe trouble breathing, swelling around the eyes or face, sudden confusion, or a severe headache with a stiff neck. Contact a clinician if the blockage is persistent, repeatedly returns, prevents sleep, follows an injury, or stays on one side. Fever with worsening facial pain, reduced vision, or feeling very unwell also warrants prompt advice. Children who struggle to breathe, drink, or stay alert need urgent assessment.

What cause best fits my symptoms and timing? Should I try saline, allergy medication, or another option? How should I use it, and when should I be examined if the blockage remains?
