Clear mucus and a runny nose

Allergic rhinitis often causes repeated sneezing, nose or eye itching, and symptoms linked to dust, pets, or outdoor allergens. A common cold may add sore throat, cough, tiredness, or congestion. COVID-19 and influenza can also begin with respiratory symptoms, so the full pattern and local testing advice matter. Sinusitis is more concerning when facial pressure, blocked drainage, or symptoms that worsen after initial improvement develop.

Drink regularly, rest, and use saline nasal spray or a gentle saline rinse with safe water. Avoid smoke and other irritants. Wash hands and cover coughs or sneezes when an infection is possible. If symptoms follow a predictable allergen, reduce exposure and ask a pharmacist about suitable allergy treatment. Check with a clinician before using decongestants if you have ongoing health conditions or take regular medicines.

Seek urgent help for trouble breathing, chest pain, confusion, severe weakness, dehydration, or swelling of the lips or face. Arrange medical advice for a high or persistent fever, severe facial pain, symptoms that are worsening, or symptoms in a young child who is feeding poorly. Follow current local guidance for testing and limiting contact when COVID-19 or influenza is possible.

Ask whether your symptom pattern suggests allergy or infection, whether testing is appropriate, how to use a saline rinse safely, and which medicines are suitable with your other conditions.
