Hi, just today I noticed a large cakersore-type crater deep inside my vaginal wall. I have never had sex, so it can't be an std. I have gotten cakersores my whole life inside my mouth, but I have never had any anywhere else. I have never had this before and it worries me. I just was very sick for 2 weeks with a viral infection and just got better a few days ago, so I don't know if that would be related. I've seen lots of posts about herpes or other stds, or things on the outside of their vaginas, but not any on the inside wall. It also does not hurt, but I had some discharge that made me think I was starting my period, but it would be 2 weeks early if that was and it never started. Then I noticed the crater, which was a lump at first and now is indented. I'm worried because I know it's not an std and I don't know what else it could be. Can you get cankersores inside of your vagina?
