I just wanted to throw this out there b/c I know I personnaly was going crazy with this until I figured this one out. I wondered if perhaps you are using yogurt or garlic regularly? I was, and this was a source of allergic reaction for me that presented as vaginal(and elsewhere) discharge and itching. Since I eliminated these the itching is definitely subdued unless of course I slip up and have something I have a sensitivety to. HTH
