I know how that feels. I don't get cramps and pain and stuff at all...most of the time. But the two times that I have had pain all I could do is lay there huddled in a ball and cry; moving a toe hurt like hell...and the last time, I woke up to "AAAAArchie" because my mom left it on the bedroom. That was a pleasant wakeup call. -_-

So even though I don't have your problem, I TOTALLY sypathise.
