Oh, I'm sorry you're in pain. If it's trapped gas, chewable Gas-X would help and lay in bed on your left side. I don't know why that helps expel gas, but it does. A heating pad on the spot where the pain is helps, too.
Dx'd Crohn's in '99 at 28. Proctocolectomy and ileostomy in '06.
Disease-free, medicine-free, and very thankful to be healthy again.
