A member asked:

What does ulceration of the mucous membrane of the nose do to you?

A doctor has provided 1 answer

Infection risk: The nose is one of your primary lines of defense against disease. The nasal membranes filter most of the airborne viruses, bacteria, pollutants, and other nasty stuff that you're constantly inhaling into it. When those membranes are damaged, the nasties go directly into your air passages and increase the chances that you will get sick.
