Well, earlier this year around october, I just woke up one day for school and my vagina hurt really bad. I noticed there was a canker type sore there... I didn't think much of it until I noticed it hurting when I walked and if I use the bathroom, if my pee would hit the sore it would sting so much. I waited like a week and went to the doctor. I'm currently 18 years old, and I'm SURE I haven't had sex with any one I'm a virgin still. I went to go get it checked and got tested for herpes & yeast infection... So the results came back and I didn't have herpes, but yeast so the doctor prescribed me some cream. In 7 days, it was gone. Now, I think it CAME back - but it's not in my vagina this time it's like closer to my butt??? I still have the cream, from last time do you think I should use it? Do I have another yeast infection? I've been looking up forums on google and some people have gotten a sore or blister from a yeast infection which is rare yet not unlikely?? Help please??? I would appreciate it, thanks!
