Back in 2000 I had a bowel resection due to crohns disease. I don't get any cramping with my BFS really but I have noticed the odd time I do get cramping around where my incision was. I have a rather large abdominal scar from my right side to just past my belly button so it spans about 12 inches. Is it possible that the damaged abdominal muscle could freak out like that from time to time? I notice it cramps when I stretch or strain it somehow, or move a certain way.
