water discharge from the nose medical term
Mucus traps bacteria and debris and prevents it from entering your lungs. In some casesâsuch as when you have a cold or allergiesâmucus may flow out of your nose or down your throat instead of staying in your nose. When mucus comes out of your nose, it is called nasal discharge, or more commonly, a runny nose. Nasal discharge can also be called post-nasal drip or rhinorrhea.
