Agree with the others that a high intake of fibers could be the culprit. Also, it's normal to flare up when you are on Remicade. I have been for it since 2016 and I can get severe flare ups. You mentioned also that this is your fourth infusion. I remember that for me it kicked in after 9 months from starting it. Hope you feel better soon
