I'm sorry to hear you may be going into a flare...not fun.
Surgery is normally an option once Remicade has failed all together. If you're going into a flare, they may try you on a steroid to try getting it under control. What form of UC do you have? I had pancolitis and was limited to certain forms of meds, meaning the rectal ones. However, there are so many people on here that have such wonderful success with them for their conditions.
Your GI may also try bumbing up your infusions to every 6 weeks to see if that makes a difference...you could always ask.
How do you feel after your infusions? I only had 5, as I felt good the day of and rapidly became just as sick as I was before the treatment.
Keep us posted regarding advice you received from you GI! I'm really curious how you're going to be treated, if you are going into a flare. : )
