I was diagnosed with IBS after food poisoning in September of last year... I have had every test done... sigmoidoscopy, barium enema, upper and lower GI follow thrus, colonoscopy with biopsies to test for Chrohn's... I guess why I am so frustrated is that I was doing okay until the middle ear virus... I took no antibiotics because it was a virus... I lost about 15 pounds at the beginning and was unable to eat as well... now it seem's like I am back to the start and I feel like I have no life... I go to work.. feeling crappy in the am but I go anyways... feel better and have a bagel for breakfast... whammoo feel lousy for a while... then feel better have lunch and feel lousy.... go home and eat supper and then it really lets loose... I usually sit on the toilet for at least 2 or 3 hours sometimes D sometimes not... I have alot of pain and the only thing that helps is rocking on the toilet and deep breathing and taking buscopan... I have been eating my safe foods and still pain but not as bad as if I ate the wrong foods.... help!!!
