Hey aunt jess, idk what’s goin on foreal rather it be my underwear kausing little bumps on the inside where my thigh and pelvis meet. But just recently like 3 days ago I had 2-3 bumps on my buttcheek, I didn’t wake up with them neither, they came along the day but I was sleep a lot Sunday as well, they were itchy yes, didn’t start hurting till Monday after the scratching, and by late Monday evening I felt them start to scab up……..I have had some oral about a month ago and was told all clear……but the funny part is I have seen a bed bug in my bed recently never ever had to worry about this problem???what do you think caused them to pop up on my butt….and with the bed bug my mom said it was impetigo that’s why I had hecka bumps on my right shoulder down bicep……what is the cause of the buttock bumps, at first the 3 where apart with 2 being nearby but a gap inbetween and after Monday they all scabbed up together even though they wasn’t clumped together……….
