Probably the absolute last thing you want to do when you have cramps, but, exercise. Nothing too abdomen-heavy (like sit-ups or crunches), but running, biking, or swimming can work. It gets the blood moving, and lessens and/or prevents cramping. It doesn't work for everyone (and if you keep thinking about your cramps it *definitely* won't work), but it works for the majority of people. Hope it helps?
