I've tried everything and
I mean... EVERYTHING. Diflucan (for a full month), Terzol, Boric Acid
(for a full month), probiotics, yogurt, garlic, tea tree oil, apple cider vinegar...you nane it!
Went to Gyno and 3 times they looked under scope and saw yeast. When they did the culture, it was neg, but I was always using or had very recently used some form of treatment, so I think it's a false neg. The only time I get relief, amazingly, is during my period.
