HELP !!!!!! #TMI THOUGH !!

I get these little bumps/pimples in the most random spots on my body. I’ve had some pop out on my hips, my stomach, the top part of my vagina, my armpits , my boobs & even my butt cheeks. I get them pretty often too which is why I’m worried now. Does anyone else get these? How do I get rid of them or avoid from getting them?! They all look different too & range in sizes. Some are purplish around the edges and some are extremely red/pink. Some have puss and some are just a painful to the touch skin bump. Some are huge and some are tiny, I just don’t get it ! I’m embarrassed & It’s driving me crazy. I’m getting ugly little dark spots and scars all over my body from it !
