Welcome to my world.
I get a side cramp 80% of the time when I run. Somtimes it's really bad and other times I can keep it at bay, so I can keep running.
I haven't figured out how to keep it from happening, other than running slowly and breathing deep. If it gets really bad, I jab my fingers into the cramp and that helps too.
I hope that one of theses days it just stops happening.
