So I had this red pimple on my thigh, close to the buttocks, it was red and kinda swollen, didn't hurt, had no head,
it got worse since it's an area I sit on and is moving all the time, 
It got a head, and after picking at it a bit, I noticed that it's not ready for me to touch it, and just used benzoyl peroxide to clean and help with it, 
right now I'm using antibiotics to help with the pain, it clearly has a lot of pus clogged up, which I am not touching and just using warm water and alcohol to clean, and I just wrap it up with sterile gauze pads (which everytime I change have yellow pus on it, had some blood in the first few ones but not anymore) swellness came down as well. Should I just keep treating it like I wrote, or could it be something more serious? It's painful, but not too much, red - but not swollen. I added a photo of what it currently looks like, excuse the quality.
