About 1 month ago I got a red bump in my pubic region. It felt tender and it had a white head on it much like a pimple. It also felt like there was a hard lump under the white head. I have sever acne on my face, chest and back with a lot of white heads so I thought maybe it was just a pimple. I popped it and yellow/whitish puss came out (much like the pimples I have) and it bled a bit. I cleaned it and it went away. A week later three of these pimple-like things showed up. They were exactly the same as the first one, big, red, and sore with white heads. They were there for a few days and they go to the point where they were really sore so I popped them to relieve the pressure. Again, whitish/yellow puss came out and they bled. They went away for about 1 month and now I have one again. It is very sore, I did pop it with the same results. I have not changed the type of soap i use, nor have I changed my laundry detergent for the washcloths I use. I do tend to sweat a bit, more so in the summer. Would this be a cause? Are they due to a STD or something like that? Or are they just pimples like I have in other areas of my body? Any information would be helpful.
Thanks
