A viral infection (the common cold) is the most common cause of a stuffy and/or runny nose, but allergies, influenza, and sinus infections also may cause these symptoms. Less commonly, anatomical obstructions (e.g. a deviated nasal septum, foreign bodies) may lead to nasal congestion.
As well as a runny nose with clear discharge, as you have, it can also cause sneezing, nasal congestion, or itching.Less common is chronic non-allergic rhinitis. People with this also have a constant runny nose, but there is no identifiable allergy causing the symptoms and usually no noticeable itching and sneezing.
