It sounds like they are treating you for IBS. DO you have any diarrhea with pain around your belly button area or joint pain? I take Imuran and Asacol with the occasional prednisone and that seems to be working well. It's hard when doctors change I also recently just had to take my bx results to another gastro because my current one, he's great, he retired damn it! But it's almost like you have to start over with them it's so frustrating.
That flank pain is classic of Crohn's. No amount of "Metagenics Ultrainflamx" is going to help. See a gastro. about your options. Crohn's is a very complex disease and tenacious.
I also have a dull ache in the right hand side which is now creeping up into my Right Kidney........It took a while before I was diagnosed with Crohns (since May 2008), as all my blood test results and scans were coming back normal, which was so frustrating, as, I also was being treated for IBS which I knew it wasn't as I have had IBS for 10 years! However my gastro suspected that it may be something more so referred me to senior gastro, and it was from a special ultra sound that I was diagnosed as there was no mistaking the inflamation in the ileum. I'm now on Rafton 9mg and Imuran 100mg but speaking to my gastro last week, it's possible that I may be put on methotrexate, as I am Steriod dependant and if I can't reduce the Rafton next month then the Imuran is not working.
