I cannot take constipating medicines. I am told I have a motility problem that is not: colonic inertia, gastroparesis, or pseudoobstruction.The only "real" problem is pelvic floor dysfunction. Being constipated one day shouldn't "hurt" so much. For two days after the colonoscopy I was in agonizing entire lower bowel pain.Zelnorm worked last year (03). It did nothing this year but create water which stayed in my sigmoid colon.
