As far as I know, I've had this since I was very young (I remember it) but I just started noticing it again now. It's kind of long, and hard like a bone and I'm not sure how deep it goes. It's not a lump or any kind of wart-- like I said, it's like a bone. I doesn't hurt, doesn't bother me, and doesn't affect bowel movements. It's just there and I have no idea what it is. Any help?
