My GI was also really reluctant to put me on Entocort, but he did and I stayed on for about 6 months. This was primarily to address joint pain in my hands - on the theory that bowel inflammation was causing the joint pain and redness. It definitely worked, but after a few months we needed another approach and I started sulfasalazine (on top of the pentasa I'd never stopped taking). I weaned off the entocort and built up the sulfasalazine - there was one week during this transition where my hands hurt but other than that I've been pain-free (in my hands) for almost a year. What a blessing.
On the other hand, now I have knee pain and arthritic changes in my sacroiliac joint, so it's time for another meeting with the GI to figure out what to do. All this time my bowel symptoms have been mild to [rarely] moderate.
I think entocort is an excellent option to buy some time for you to heal, June, and to think about other meds. And an enteral diet is also a great idea to get you over this nasty hump.
