Cramping is a pretty typical symptom for Crohn's. My doctor prescribed bentyl to help keep those at bay and it seems to work pretty well.
You don't have any other symptoms like a distended stomach do you? I know sometimes that coupled with cramping and/or abdominal pain below the belly button in general can indicate some sort of obstruction. If that's the case then you can try and combat it with low residue or liquid diet.
I'm sure other members will be along with more suggestions though.
In any case, I hope those go away soon :)
