Today I had an itch and scratched it only for my finger to have a small amount of blood on it. The itch was a few inches above my anus (on my "butt crack" towards the top). It bled a little bit more so I decided to look in the mirror. I found what seems to be a small hole about 1-2 mm in diameter which the blood was coming out of (not a cut or puncture, what seems to be a hole). It is still bleeding very little and the amount of blood is not a lot, but it is constant (a drop or so every minute or two).
Anyone have any idea at all what this could be? If it does not heal, I may see a doctor soon about it but wanted to see if anyone had any advice to offer.

Thanks a lot
