About 8 weeks ago, I woke up with a big pus-filled pimple like thing about an inch below the start of my pubic hair. I popped it and pus came out. It was a big bump,I put camphophenique on it and it did nothing, because I thought it was a bug bite. About a week later it filled with pus again and I popped it. The bump was pretty big for about 3 weeks. I put a needle in it to see if anything was in there again after another week, a little blood came out. I put ice on it. It finally went down flat, but there is still a mark left and it is red. It does not hurt, but it the redness will not go away. I then thought it might be herpes, but there was no blister or open sore, or pain. What can this be? Why is it taking so long to heal? I have been putting different things on it, but nothing seems to help. I even tried herpes treatments from over the internet. It just seems like it is being irritated more. What can I do to heal this?
