Suggest Treatment For Lower Abdominal Pain,diarrhea And Acid Reflux

Less than a year ago I started to experience loose stools/diarrhea. It starts out with a normal bowel movement, but at the end it would be soft that I would be wiping myself most of the day. Now it has come down to having 4-5 movements a day, which are very soft and rope like and am constantly wiping myself. Within the past year, I have been through 2 Colonsoscopy s, A Sigmoidoscopy, Upper Endoscopy and Exploratory Surgery where they have removed my appendix. With all of this done, they say everything came back normal. They have ruled out Colitis, Crohn s Disease and Diverticulitis. It seems every time I eat, I have to go to the bathroom, not right away, but an hour or two later. Sometimes I just have the urge. I have also experienced a lower right side pain that comes and goes with this. They have told me that it s probably an inflamed muscle. I am at my wits end with this problem as I cannot go very far from home. If I don t eat anything, then of course I am fine. When I eat my acid reflux flares up so bad, that it feels like there is something heavy on my throat. I am on Omerprazole for the reflux. Could I possibly have something wrong with my Digestive System? Please help me.
