Hello, not sure if this was the right place to ask this question, so if so, I apologize. For a few months now, I have noticed a bump on my clit that randomly appears and disappears. It's not on the skin, but underneath. When it appears, it hurts to touch. It's usually the size of the top joint to the tip of a thumb. Then during the day, it will dissapear and then reappear within a few hours. I know it's not cancer, because cancer doesn't just come and go. Could you help me and tell me the possibiblitie's of what it is. Also I jsut had a pelvic exam not too long ago, and I'm clean of sti's. I've been with the same faithful guy for a year now, and he's never cheated on me and is also clean. So that rules sti's out of the question. Thank-you yet again.
