I have some itchy pimple-like small bumps on my labia majora. They came not long after I started my period. They are NOT inside my vagina, so it doesn't hurt when I urinate. They also are NOT open sores. I've never gotten this before, though, so I'm a little scared that this is a bad sign. Do you think I have an STD? I've been tested before, and I was clean. What can this be? I've been applying topical cream, and they've been healing. They basically feel like pimples. They hurt a little before, like pimples when they are "ripe", but then they don't hurt or anything anymore. They used to itch, but they stopped itching. I "popped" one today.. and very little puss came out. They seem like pimples. What can they be?
