I have a a very painful bump near my vaginal opening. It started out as a little pimple looking thing so I popped it and let it go. A couple of days later I noticed a bump back in the same spot and scratched it. Now it's extremely painful, red and looks like a burn. I also found a bump a little higher up witch I assume was an infected hair so I pulled the hair out. Now both are extremely painful red and sore. I'm on an antibiotic for a UTI at the moment. Could anyone tell me what might wrong?
