I ve been feeling a mild burning sensation in my vagina and vulva area and I have no idea what it is. It burns when I urinate. I went to 2 different docs and they tested me for yeast and fro bacterial infections and everything came back normal. This just started out of nowhere. I don; t have any discharge and everything LOOKS normal but I still have the burning. I feel it sometimes in my anus area as well but mostly in the vulva. Does anyone have any idea what this could be?
