About a week ago I noticed a red rash kind of thing on my groin area, near my leg. It developed into what looked like a scratch and was very itchy. It developed into a scratch and now has a big scap on it. It has been a bit painful. A few days ago there was puss on it. Should I be worried? Is it something serious? It's awkward to talk about it with anyone because of its location. I haven't done anything to it or put anything on it, only a bandaid. Should I be doing anything? Please help!!!!
