I have seen 3 GI specialists to get second (and third) opinions. Other diagnoses have been (1) symptomatic diverticular disease and (2) IBS. My current GI specialist arrived at the SCADD diagnosis after trying out a number of treatments in succession. He was using the treatments to alleviate my symptoms, of course, but also as a diagnostic tool. At that time about 2 1/2 years ago, I was having sudden attacks of severe abdominal pain. The medication that finally worked for me was mesalamine (delzicol), which I continue to take. I also have irregular motility. I take miralax and citrucel for constipation, and other medications for visceral hypersensitivity. I rarely have severe attacks of pain these days, but I do have mild pain – localized on the left – from time to time. And I continue to have irregular motility. I have not been able to figure out which foods – if any – aggravate my symptoms. This has been an ongoing difficulty.
