What should you know about frequent sneezing and runny nose?

Clear, watery discharge with itching and watery eyes often accompanies allergic rhinitis. House dust mite allergy may be more noticeable indoors or on waking, while pet allergy can follow contact with an animal or contaminated clothing. A common cold may add sore throat, cough and feeling unwell. Influenza and COVID-19 can also cause respiratory symptoms, often with fever, aches or marked fatigue. Sinusitis may follow congestion and produce facial pressure, thicker drainage or reduced smell. Irritants such as smoke, dust and strong fragrances can cause symptoms without infection.

Note the colour and character of the discharge, exposure to triggers, temperature, cough, throat symptoms and how quickly the episode began. Wash hands, rest and drink fluids during an infectious illness. Reduce dust, smoke and fragrance exposure; keep windows or ventilation appropriate for the setting. Saline spray may ease dryness. Ask a pharmacist about symptom relief and check before combining products, especially if you take regular medicine or have another condition.

Seek emergency help for breathing difficulty, swelling of the face or throat, faintness, confusion or severe weakness. Arrange prompt assessment for chest pain, dehydration, severe facial pain, eye swelling, persistent high fever, or symptoms that improve and then sharply worsen. Consider medical advice when symptoms keep returning or interfere with sleep and work.

Does this pattern suggest allergy, a viral illness or sinusitis? Should I test for a respiratory infection? Which treatments are safe with my existing medicines? What warning signs should I watch for at home?
