Medical Definition of Nose, runny
Nose, runny: The production of extra mucus by the nose. Rhinorrhea is the medical term for this common problem.

Mucus formation is also part of the histamine reaction to allergies and of the body's defenses during respiratory infections.Source: MedTerms™ Medical Dictionary
