Glad you finally have a coherent report and a good one! Fletcher has IBD, and when his arthritis started getting worse this last year, (in his hips now, as well as his shoulders ) we went to a combination of Tramadol and Metacam. So far, so good! I don't know how you feel about alternative medicine, but I have started giving him Yucca Root drops, and it has really made a difference, to the point that I am able to cut back on his other meds, and it hasn't triggered a flare-up. I can understand if you don't want to take the risk, though.
Oh, and he gets a milk thistle capsule everyday, now that he is on daily Metacam.
