I'm sure you've already looked into this, but have you changed your diet or meds recently? It probably wouldn't hurt to get a set of labs run, just the basics like CRP, CBC with diff, and complete metabolic panel. You may want to ask for a calprotectin done, too, as that is usually quite accurate in detecting any inlfammation in the GI tract (much better than a lactoferrin would be).
That's too bad about the Remicade and Cimzia...I feel ya on that. The day that my GI told me no more Remi I cried. It was so nice, like IBD heaven. The cimzia actually put me in a weak remission, but I developed an allergy to it. If I need to, I would be willing to try it again with a pretreatment of prednisone and be monitored.
