Ok so a few days ago, I felt a pimple on my butt & I popped it thinking it was a regular white head. After, I started feeling pain but it was bearable. The next day I started feeling more pain & seen that a white head came back so of course, my hardheaded self popped it nothing thinking anything else. After I did though, I bump started forming leaving that part red. It's been about 5 days now & it hurts! I see two white heads forming again & the lump is about the size of a nickel, maybe a quarter even. I don't want to continue popping it because of the pain making it difficult to sit let alone sleep. I hear putting a warm rag can help. I just want to know exactly what this may be & how to get rid of it. Please & thank you!
