Hi everyone, I have had this bump on my inner left butt cheek for about a week or so now. I had one before but it had went away in about 3 days and it just resembled an ingrown hair. But this one didn't go away after three days. It began to get extremely irritable and I could hardly sit or walk. Today it finally just exploded with no warning. The pressure is definitely gone, and it's still a bit tinder. It only exploded blood though, and that's what really has me worried. I cleaned it up as much as possible and I put a band aid on it. I really want to know what it was and if I should be extremely be worried and see a doctor. Anything will help!
