If you have a runny nose, are you sick?

A cold often brings a runny or blocked nose with sore throat, cough or feeling unwell. Influenza and COVID-19 may also cause nasal symptoms, often alongside fever, aches or marked tiredness. Allergic rhinitis can cause repeated sneezing, itchy eyes and clear discharge without an infection. House dust mite allergy and pet allergy are possible triggers. Facial pressure, reduced smell and thick discharge may occur with sinusitis, although symptoms alone cannot confirm the cause.

Rest, drink fluids and wash your hands regularly if an infection is possible. Saline nasal rinses may ease mucus; use safe water and clean equipment. Avoid smoke and other irritants. Consider staying away from vulnerable people while fever or new respiratory symptoms are present, and follow local advice about COVID-19 testing when relevant.

Arrange medical advice for breathing difficulty, chest pain, confusion, dehydration, severe facial pain, swelling around an eye, a persistent high fever or symptoms that are worsening rather than settling. Seek urgent help for severe breathing trouble or blue or grey lips. Children, older adults and people with long-term conditions may need earlier advice.

Ask whether the pattern suggests infection or allergy, whether testing is appropriate, and which nasal treatment is safe with your medicines and health conditions.
