I have had a TERRIBLE vaginal itching for over a year. I have been to the gynecologist and taken pills, been prescribed cream-clobetasol prop 0.05%--- I am on my 5th tube of that.. been prescribed medicine for yeast infection. Gynecologist even did a bioposy that came back inclunclusive.. Nothing is working---- now I am noticing knots on the inside of the vagina. I have not been sexually active for 9 years.. Can you help ???
