A couple of days ago when I woke up, the right and upper portion of my anus were protruding a little - it was slightly painful, but nothing major. I had overeaten the night before, and had been overeating over the holiday season. Normally I don't eat so much.

I was able to push the protrusion back in, but it seems to come back out whenever I use the toilet. I feel somewhat bloated still, and am using the toilet more than usual.

Is this something that may go away on its own, which is simply related to holiday excess, or could it be something more systemic for which I should be seeing a doctor immediately? I have heard that things like this could be related to colon cancer.

Any help much appreciated!!
