When I'm in a flare, my CRP is always elevated, together with the WBC. My disease is also located in the terminal ileum, and I'm having blood tests every 3-4 months just to be on the safe side, and not let the situation get out of control. Why does he want to try Remicade so soon? My GI told me that Remicade is used only if all the other medicines have failed, but then again maybe here in Greece they handle Crohns differently.
Anyway, try not to stress too much about it. The sure thing is that there are a lot of options, it just takes some time to find what's right for you.
