irritable bowel syndrome
"I had horrible stomach pain before during and after bowel movements for 3 years before I saw a GI doctor and was diagnosed with colitis (not ulcerative). The GI doc prescribed me these after she saw spasms during my colonoscopy.  They definitely help take the edge off. I use them a lot to nip the problems in the bud, so to speak. Once in a while though my symptoms are too severe for this medicine to work. But 90% of the time, this saves me a lot of discomfort."
