I have been getting a lot of cyst-like bumps ON both my buttocks cheek, since they get so painful, to the point I cannot sit down properly, I try to pop them, and once I do, some sort of puss comes out and then when I squeeze more, blood comes out. Since this has happened so many times, I now have, what seems to be scarring. I want to know why this keeps happening, what it is exactly, how to prevent it and how to cure/treat the scarring? Please help, I really truly need it.
