If you're going from the rectum that often, you could have an infection. I get yeast infections in my rectum sometimes (antibiotics or even hot humid weather) and an oral course of diflucan clears it up. My symptoms are "the urge" and going more often than normal (for me once or twice a month). I'm not sure a yeast infection could/would cause the cramping, another possibility is that you have some other type of infection going on.
Hope you get your insurance soon, I really think you should have it checked out.
