Two days ago I noticed a small lump near my rectum, under it, between it and my tailbone. As uncomfortable as I am about making a post on the internet about this, it has been bothering me consciously. It doesn't pain, and it's the size of a wart, and kind of feelings like a wart/pimple. It seems more above the skin than under. It's not big, maybe a little smaller than a pea.

I have no idea what it could be, but I'm wondering if I should be worried or if I should let it clear up on its own.

Thanks,
Mark
