What actually is nasal discharge?

A doctor has provided 1 answer

Nasal response: Fluid produced by the nose in reaction to a pathogen, allergen or foreign body. It is the bod's attempt to flush out the offending particle in the nose. Your nose produces a liter of post-nasal drainage a day in its attempts to cleans the air we breathe, preparing it for the lungs, by the sweeping mechanism of the cilia of the nasal lining.
