Hello
I have these open sores on my underarm. They sart as just red painful bumps and then they turn into open sores, they look like there is an actual hole in my skin. They are pretty small but they bleed and have like a mucas come out of them when they turn into open holes. They have lasted a month now and havent gone away. Is it an infection, or skin irritation? I have no idea and need some help.
