Sore throat and stuffy nose: what to know

The Common Cold, Influenza and COVID-19 can inflame the nose and throat at the same time. Allergic Rhinitis can cause a blocked or runny nose, throat irritation from drainage, sneezing and itchy eyes, usually without the whole-body feeling of an infection. Acid Reflux can irritate the throat, although it does not usually explain a blocked nose by itself.

The colour of nasal mucus alone does not identify the cause. Fever, body aches, cough, exposure to illness, itchy eyes and the length of symptoms provide more useful context. Strep Throat is less associated with a stuffy nose than viral illnesses, so a clinician considers the full pattern rather than one symptom.

Drink regularly, rest, and use warm fluids or throat lozenges if they suit you. Saline nasal spray or a gentle saline rinse may loosen mucus; use a properly prepared product and clean equipment. A humidified room can feel soothing. Ask a pharmacist before using a decongestant, especially if you have high blood pressure, heart problems, glaucoma, are pregnant, or take regular medicines.

Wash hands, cover coughs and sneezes, and avoid close contact when fever or active respiratory symptoms are present. Do not start antibiotics without an assessment, because they do not treat viral infections.

Seek urgent help for breathing difficulty, blue or grey lips, inability to swallow fluids, confusion, severe dehydration, or rapid worsening. Arrange medical advice for persistent high fever, severe facial pain, chest pain, unusual drowsiness, or symptoms that improve and then become worse. People with significant immune problems, very young children, and older adults may need earlier advice.

Ask whether the pattern fits an infection or allergy, whether testing is appropriate, which nasal treatment suits your medical history, and what duration or change in symptoms should prompt review.
