Hi,

I have an occasional problem that happens right before I need to go to the rest room. Sometimes I'll have this intense, spasm like pain in my rectal region which comes in slowly, hurts pretty bad for about 3 seconds, and then slowly fades out. I have to stand still and let it pass before I do anything else.. I also notice:

1. It only happens when I'm standing, never seated
2. It almost always occurs right as I enter my bath room. If I've been holding it then it might happen outside, and then several times as I look for a stall, but this is very rare. (its happened maybe twice) Because it seems to happen right as I come to the bathroom I think it may be caused mentally (as I'm ready to go)
3. When I do my business there is no pain at all.

I'm 21 and in good health, eat well and go to the gym regularly. The pains happen maybe once a month as I'm going to the rest room. It only happens if I feel I need to go but delay it a bit (maybe an hour because I'm working on something) I don't think holding for just an hour should cause spasms like that though. I use the bath room on a regular basis and certainly don't make a habit of holding it in. Any idea what is causing this?

Thanks
