I've been on Remicade for 5 or 6 years now, and I've never heard of it making strictures worse. Not that it couldn't. It made my strictures much better. Could be that your BM's are firming up and it's making the stricture more noticeable? I still occasionally get pain in my gut, mainly because the strictures are still there, just not as bad as they were.
Is this your first infusion, or have you been on it for a while?
