What should you know about cold sneezing runny nose?

A common cold can cause a runny or blocked nose, sneezing, sore throat and cough as the illness develops. Allergic rhinitis commonly presents with repeated sneezing and a watery runny nose, especially when the nose or eyes itch. House dust mites and pets can trigger symptoms in susceptible people. COVID-19 and influenza may also include nasal symptoms, usually with other features such as fever, aches, fatigue or cough. Sinusitis is more suggestive when facial pressure, thick drainage or persistent blockage becomes prominent. The symptom pair alone cannot distinguish these causes.

Rest, drink fluids, use saline spray or drops, and clean your hands after blowing your nose. Note when symptoms begin, whether they follow dust or pet exposure, and whether fever, cough or body aches occur. Reduce contact with a suspected trigger when possible. A pharmacist can discuss allergy medication or other symptom relief, taking account of age, pregnancy, chronic conditions and regular medicines. Avoid doubling ingredients across combination cold products.

Seek advice if symptoms persist, recur frequently, impair sleep, or include significant facial pain, wheezing or loss of smell. Arrange prompt review for a persistent fever or symptoms that worsen after initial improvement. Emergency help is needed for severe breathing difficulty, confusion, fainting, or sudden swelling of the lips, mouth or tongue.

Ask whether the timing suggests infection or allergy, whether testing is useful, which treatments fit your health history, and what warning signs should change your plan.
