Tmi but help??

Kate

I think this is a staph infection but I can’t be sure. I got an STD test recently so I know it’s not that. But these red dots appeared on my butt like last week and then briefly went away but are back again. They don’t hurt but they are super itchy and annoying, I’m just wondering if anyone else has had this and if there’s any home remedies that I can use so I don’t have to go to the doctor
