About six months ago I noticed a small indentation develope in my skin in the area just beneath the tip of my tailbone inside the cleft of my buttocks. It is a small hole barely the diameter of a cue-tip. On a couple of occasions I have had blood come out of this "hole" or indentation, sometimes in small amounts sometimes larger but never more than a tablespoon or so.

Recently I took a shower to try and flush out the hole, thinking it may be an infected boil or pimple or something. Upon applying pressure to the area blood would exit the hole, and eventually seemed to stop or empty out.

There is no pain in the area or swelling. No pus has ever come out of the hole. There has been no blood until just recently when I was involved in a game involving lots of physical activity (sports). Upon removing my undershorts I noticed that I had bled a small amount and that applying pressure caused more blood to come out.

I have no idea what this is, where it came from, what it is called and if it is serious or not. For the time being it is simply inconveniant to fear ruining my pants or undershorts by bleeding all over them.

I would greatly appreciate anybody that could tell me more about this bizarre condition I seem to have acquired.

Thank you
