Hi. I registered for this site just so I could answer your message, and I had to wait forever for the confirmation email.
I KNOW WHAT YOU ARE GOING THROUGH!!!!
What you're experiencing is called rectal temesmus, and it's one of the banes of my life. It's caused by inflammation in the rectal region. Inflammation further up is actually more dangerous to health, but rectal inflammation is extremely uncomfortable and difficult to treat. I've had spasms so bad I'm crying on the toilet.
I was recently hospitalized for this. My entire sigmoid colon was so inflamed that almost no stool could get through and I was extremely constipated. All I passed was liquid and gas, and the spasms were excruciating. I'm now on prednisone, three different types of topical medications (cortenema at night, canasa in the morning, 5-asa enema in the afternoon - after I type this, actually).
There are three ways I've found to deal with this - besides the medication. #1 recommendation is to lie as still as you can in bed. Do not move. Because the other solutions involve medications that are better not to take. One doctor I went to prescribed Robinal Forte, which worked at the time (no more), but cause horrible drying in my mouth and eyes. I had to walk around with water or I couldn't swallow. The usual class of drugs used to treat this are opiates, but those are both constipating and addictive so there is a downside. Codeine isn't strong enough for me anymore (the spasms have been horrid). In the hospital they gave me intravenous morphine, which worked.
Right now the spasms are greatly subsided between the predisone, enemas, suppositories, and bed rest. I expect that in a few more days I'll actually be able to walk around like a normal person again.
Good luck!

Oh wait - after writing all this and seeing the previous reply, I realize you may not have seen a doctor yet. See a doctor. You may just have a little inflammation around your rectum - forget what that's called. It's a very mild and limited form of ulcerative colitis (I have UC, but through my entire bowel.) They'll give you a week of cortenemas at night and all better. Are you experiencing pain with the spasms?
