Does MRI contrast cause/trigger a flare up?

Last Thursday, I had an MRI dynamic study to investigate the cause of rectal soiling. When I was on the machine table and after I was given 3 enemas (50 ml) each, I started to feel throbbing pain in my colon. This happened twice and then things became better. The following day, I had violent diarrhea to the extent that I could not leave the toilet and was screaming out of severe pain. I thought I had to rush to the ER but after taking antispasmodics pain was bearable. On Saturday, I had another diarrheal bout and so I took Imodium. Ever since I started severe ileal pain and no antispasmodic soothes it. I also haven’t had any bm ever since and if I try, the severe pain I had that made me scream returns. This is weird. I have been doing well on Remicade lately and even if I had pain, it was bearable. This time no. It’s a typical flare up that I used to have before starting Remicade. I also lost weight that all people, who know me, noticed. Does MRI contrast trigger a flare up or does the frequent straining I was asked to do as part of the study (2 times pre enemas and 8 or 9 times post-enemas) cause the flare up? I did the study 7 years ago and it only caused me vomiting for a couple of days. This time, it’s different.

Oh, my goodness, Clo. My fistula is supposed to have healed based on last MRI last March. I can’t fancy that my GI would order a test that would throw me into a flare up. I can’t figure out on my own how to control the pain. I’ll see him tomorrow and hope he has an answer for what happened and he can control the flare up without upping any doses. It’s very sad /:
