Ha, ironically I was on Remicade for less than a day. I was in hospital for uc flare. Finally got through all testing and approved to administer. 8 am they gave me remicade. 3 pm ct scan for pain i had been having for a few days. 630 in surgery for ruptured colon, woke up with the ostomy bag. I think I ruptured a few days before the surgery and Remicade, that's when the intense pain started.
