hiii so I don't really know how this works but I have this weird pimple like things on my butt. They're black and they're shaped like pimples but I don't think they're filled with puss or anything. It kinda just feels like it's filled with skin and I also only get a few of them??
at first, it sounds like you have mitesers on the skin of your butt - mitesers are more or less clogged skin pores and the fatty substance that clogs the pore does feel harder than pimple would.
Since you get only few of them and if they are not painful, chances are there is nothing much you should do about them, but if you feel like you need to get rid off them, than the best way would be by seeing either dermatologist or cosmetician.
Wish you all the best,
