I took a bubble bath last Monday morning. That afternoon after work, I experienced some irritation and noticed what I thought was a small bump on the inside of my labia (one side only). It was red and a little white in the middle. When I touched it, however, it did not feel like a bump. It was smooth. Also, it was not painful to the touch at all, no matter how much I touched or manipulated it. I put peroxide on it and it did not fizz. However, I did feel slight itching and sometimes a shooting pain in that general area hours later unrelated to movement or touching. By the next afternoon, the irritation was pretty much gone, but it still looked white. I rubbed at the white area with a wet Q-tip and the white stuff came out/off like dead skin almost (the white part was dry, not pus-like). I could not remove all of it without tweezers so the rest came off with water in the shower. It left a tiny pin-head sized crater it seems or it could be a scar. It's so small and far away from my vantage point I can't tell which it is and can barely see it at all now (by day 3, I could barely see the hole/crater). So, it was red with a white center, slightly irritated (itched/stung) for a day, flat (although the labia was swollen), and was not painful to touch. Any idea what it could have been? I was recently tested for all STDs (herpes included), all non-reactive. The only test that was not performed was syphilis. Also, I did try to see my doctor on Monday, but they could not give me an appointment until Wednesday. That conflicted with my schedule and by then, there was nothing but a small hole/scar left to see.
