Yeh -- what Flowers said
Remicade 10mg/4weeks is what finally got me to the promised land of remission.
Looks like you have tried nearly everything except Xeljanz. So if you aren't ready for surgery maybe you could try that first. Still if you are getting any response to remicade you might want to hang with it and try different doses/frequency before stopping it. It was about
2 years until I reached full remission, but I was functional after my loading doses and was able to live pretty normally so I had the patience to wait. If I had still been going 10+/times a day with bloody diarrhea I would not have stayed on it.
