Every few months or so, this bump continues to show up. It’s right under my butt cheek. Sometimes it’s on the left, sometimes it’s on the right, sometimes it’s on both. I’m so confused! It’s almost always on the same spot and it hurts like a b*!

I thought it was a zit because I have acne but I can’t pop it.

Then I thought it was a bug bite but it just keeps showing up in the exact same spot.

After a week or two it disappears like it was never there.
