About a month ago, I noticed a slightly raised surface under the skin of my labia. I didn't really worry about it, as I suspected it was simply a pimple, or ingrown hair (as I do shave every so often). However, it recently has increased in size, and has no head, nor is it painful unless squeezed. Some hairs seem to be growing from it just fine as well (sorry for the tmi). I was also recently tested for herpes 1 and 2 through an antibodies test, which came back negative, and have been vaccinated against HPV, so it's unlikely that it's an STD. Has anyone experienced this before? Any insight would be wonderful. TY in advance!
