By all means, see a Rheumatologist. But, I'd be darned if I would wait two weeks to see the gastro and then who knows how long before an upper GI w/small bowel follow thru is scheduled!
Your family doctor can script
that UGI/SMFT, you don't need to wait for the gastro. That can put you a couple of weeks ahead of the game getting a Dx and treatment for your symptoms.
Let the gastro order the Pill Camera for the small intestine if the UGI/SBFT doesn't satisfy his Dx'ing criteria.
In 2008 my Mayo Clinic gastro told me that the MRI isn't as reliable as the CT enterography yet except in the rectum. You rectum's already been seen by the colonoscopy. Mayo is working on improving the MRI results for the rest of the intestines in order to reduce the need for the massive radiation doses of CT scans. Heaven knows we get enough radiation exposure thru the years when we have Crohn's disease!!!
Have they discussed gall bladder possibilities with you? I totally agree w/others that a Barium Enema is a ridiculous repetition given the colonoscopy. There are some definite advantages to a colonoscopy rather than the BE, biopsies being an important one, but the scope is also money in the gastro's pocket instead of the radiologist's. I suspect many crohnies go thru more than one colonoscopy that really isn't necessary.
