hello, i'm new. i found this forum while searching online about a certain skin problem that i have. i couldn't find any help just looking at websites, so maybe someone here can help me out. lately i've been getting red bumps on the back of my thighs and butt. they start out as small, itchy, kind of a prickly itch- bumps. then within a few days if i scratch them or my pants rub on them too much, they get bigger and more sore. then some eventually get a small pus-filled head on them and some even grow pretty large and get hard underneath and full of pus. (sorry if that's too much info) and they are very painfull, almost to the point where i can hardly sit down. and i have to use heat compresses to drain them and make them finally drain and go away, then they leave a dark kind of scar...this problem started again just recently but i had the same type of thing happen about a year ago. i'm getting pretty frustrated,

after one goes away another one appears a few days later. i'm a very clean person and i don't sweat often or anything. anyone know what this is, or what i can do to avoid it?? any info would be helpfull, thanks.
