Hi there I understand your concern... History suggestive of upper respiratory tract infection...Drink plenty of water.
Use a humidifier.
Try nasal saline sprays or rinses.
If the runny nose is a persistent, watery discharge, particularly if accompanied by sneezing and itchy or watery eyes, your symptoms may be allergy-related and an over-the-counter antihistamine may help...take OTC antipyretics along with above... If symptoms persists more than 3 days even after OTC medication consult physician they will help you.
