What should you know about itchy and runny nose?

Allergic rhinitis commonly causes clear nasal drainage, sneezing, and an itchy nose, often without fever. House dust mite allergy or pet allergy may produce symptoms after time indoors, cleaning, or contact with an animal. A common cold can cause a runny nose with sore throat, cough, tiredness, or a mild temperature. Influenza and COVID-19 may also cause respiratory symptoms and more marked illness. Sinusitis is more likely when congestion is accompanied by facial pressure, thick mucus, or symptoms that worsen after initial improvement. No single symptom confirms a diagnosis.

Drink fluids, rest, and use saline nasal spray or a gentle salt-water rinse if appropriate for you. Wash hands and cover coughs to reduce spread when a viral illness is possible. Reduce exposure to dust, smoke, and animal dander; wash bedding if indoor triggers are suspected. A pharmacist can advise on symptom relief and whether an allergy treatment is suitable. Follow local advice about testing when COVID-19 is a possibility.

Seek urgent help for difficulty breathing, blue or grey lips, confusion, severe weakness, or swelling of the face or throat. Contact a clinician for severe facial pain, dehydration, persistent high temperature, symptoms that are worsening, or nasal symptoms that continue without a clear trigger. Ask for advice sooner if you have asthma, a weakened immune system, or another condition that raises respiratory risk.

Ask whether the pattern fits Allergic Rhinitis, a cold, Influenza, COVID-19, or Sinusitis, and whether testing or treatment is appropriate. Mention fever, cough, facial pressure, mucus colour, trigger exposure, duration, medicines, and any breathing symptoms.
