I have a large red painful bump, just slightly smaller than the size of the tip of my pinky to the first knuckle, at the top of my pubic hair line below my belly button. I have no other red marks anywhere.
I'm hoping it's not an std like herpes, since I had sex 6 days ago, and this appeared yesterday. I would believe that it's not since the location is not where herpes goes, there are no other bumps, my partner didn't have anything that I could see (and said that they didn't), and we used a condom. I have no other symptoms of an std. I get ingrown hairs that make bumps every once in a while, but never this big. Should I be concerned?
