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.
Chronic rhinorrhea (Runny nose) What is rhinorrhea or runny nose? Rhinorrhea, or a runny nose, happens when excess fluid drains from the nose. The fluid is mucus that is thin or thick, clear or opaque, and can be intermittent or constant. What causes rhinorrhea? The nose and sinuses normally produce mucus which keeps the nose moist and is typically swept back into the throat and swallowed. There are many conditions that can cause the nose to run, including: 1  Colds and flus: Mucus from illnesses can fill the nasal cavity and cause temporary nasal obstruction. 2  Crying: When you cry, tears drain through the tear ducts, into the nasal cavity, and then into the nose.
