It can be extremely difficult to get some doctors to get the tests done. I even had one doctor say patients like me are what "make health care costs go up" If the doctor won't give you the test you want, just gotta find one that will until you get it.
I would also suggest a stool test also. It's really not that bad, you just collect in a sterile cup a walnut size piece of stool. I know a guy that had a normal colonoscopy/bloodwork and later found out he had c-diff. He had it for 6 months before it was found on a stool test. He didn't have any nausea or vomiting either. May want to include giardia in that test also. Some doctors just automatically jump to IBS if you can't be diagnosed. IBS is a diagnosis of exclusion, can't be diagnosed until all other tests are normal.
Thank you so much Kakk333! I have asked the Doctor if this could be anything other than IBS and he is not willing to really do any other test (only test was a colonoscopy). I will certainly try to see if he would be willing to try the hydrogen breath test!
Also, the only thing that has really helped me lately is ultram (a pain killer) I hate taking drugs, but this is the only thing that helps.
Yes bentyl did not help me at all. The dr. told me I had IBS also. I later took a "hydrogen breath test" which came out positive. I've been on rifaximin for a week but no real change. (I get rib aches from my ibs, if thats possible?) I would see if you could get a hydrogen breath test just to see if there is some kind of small intestinal bacterial overgrowth.
