Hi, im 17 years old and I've been having this itchy , burning rash on the top part on the outside on my vagina .. It's been going on for a while now . It gets so bad that it's starting to bleed a bit from being so dry . I am not sexually active at all , so it cant be from anything like that.. And I have went to the doctor but she didn't look or anything , she told me it must be a yeast affection but the canasteen didn't help me ! And I've been using vagisal to help it but it doesnt stop it ! Please help me and tell me what it could possibly be !!
