Hi, recently I got this Red bump on my lower belly, more inward towards my right Hip bone. At first I thought it was just a pimple from my New work environment. It's a lot hotter than my old job, the I also thought maybe it was from my pants rubbing my skin. It also started to peel, then just about a week ago, it started turning a dark color, A dark Red almost blackish, as if it's been full of Bloody puss. I don't really know what is it. Do you by chance know?
