Hi Dr.Kathleen,Today I had my visit with the doctor. I took all my info on microscopic colitis, and asked that I be tested. I felt pretty dumb because he told me he already tested me for it at the same time that he had tested me for Celiac spru and I don't have any of the above. But, he was happy that I was keeping up via the internet. Now he has put me on Azulfidine. I had taken the same several years ago with pretty good results. Also, I am set up for a breath test,not for lactose but for bacteria overgrowth.
