Has your Dr. sent you in for a Colonoscopy? Maybe inquire abt that, I've had that 3 times, very sporadic and not till I was 9 mo. out, surgeon had a cat scan of my abdomen, all was ok although he thought I might be "getting backed up", went to my pc when it happened a 3rd time and he sent me for a sonogram of my gallbladder but told me up front if it didn't show anything I would have to get the colonoscopy. We'll see. I relate, the cramps have me in tears when they happen and I didn't cry at all after my surgery. Good luck!
