Okay so I went to the doc about a week ago and got treated for a STD but that same day I got really bad diarrhea. Now my vagina area is swollen and irritated. Also i think I got a rash around my anal frm the constant diarrhea. I tried preparation H for the discomfort but ithink that just made it worst. I also have skin coming off around the right outter side of my vag. I really need help because I dnt kno if its a yeast infection or something more serious Oh yea and there is no bad smell or discharge but there is white stuff, like build up when I look inside my vag im really scared
