I have been experiencing a very small amount of a light green discharge. just wondering what would cause this and how to fix it?

Vaginal Discharge: I assume you mean discharge from your vagina and not you throat or nose. This represents infection. A test needs to happen to determine which type of infection so that the appropriate treatment can be offered to you.

Green D/C: Is an odd color, and to be safe an infectious process should be ruled out. Best to get the discharge evaluated to treat it correctly.
