Given that you have had watery nose and allergy symptoms for four years, your symptoms seem more like allergic rhinorrhea than a straightforward cold. Dust, smoking, scents, weather variations, pollen, and pet hair are typical triggers. Avoid these triggers, wash your bedding frequently, keep your room dust-free, and use a mask while you're around dust. Saline nasal rinses and steam inhalation may help lessen inflammation. If symptoms are persistent, doctors frequently recommend antihistamine or anti-allergy medications like Montelukast or nasal sprays. For appropriate treatment and to check for sinusitis or asthma, it is best to see an ENT specialist or allergy physician because the issue is chronic.
