What should you know about excessive runny nose?

Clear watery drainage with itching, sneezing or watery eyes often accompanies Allergic Rhinitis. Symptoms linked to dust or bedding can occur with House Dust Mite Allergy, while exposure to an animal may point toward Pet Allergy. A cold can cause a runny nose with sore throat, cough or feeling unwell. Influenza and COVID-19 may also include nasal symptoms, usually alongside broader respiratory or fever symptoms. Facial pressure, blocked drainage or worsening symptoms can occur with Sinusitis. A runny nose is a symptom rather than a diagnosis; the timing, triggers and other symptoms matter.

Drink fluids, rest, and use a saline nasal spray or rinse if it suits you. Wash your hands and avoid sharing towels when an infection is possible. Notice whether symptoms follow dust, pets, smoke, perfume or changes in temperature. Reduce exposure to a clear trigger and keep living spaces well ventilated. A pharmacist can advise whether an antihistamine or another product is appropriate; follow the label and check first if you are pregnant, treating a child, or taking other medicines.

Seek urgent help for trouble breathing, swelling of the lips or tongue, faintness, or a rapidly worsening reaction. Arrange medical advice if drainage is persistent, one-sided and foul-smelling, follows a head injury, or comes with severe facial pain, a high fever, confusion or dehydration. A clinician can assess symptoms that keep returning or interfere with sleep and daily activities.

Could this pattern fit an allergy, infection or another cause? Which treatments are suitable for me? Should I keep a trigger diary or have an examination if it continues?
