48 yrs...HOLY COW!!! I would assume most of that time you were in remission? I should hope you wouldn't be on prednisone all that time. I suffered with UP (proctitis) for twelve years and became prednisone dependent. That crap was KILLING me! It gave me full-blown osteoporosis, uncontrollable high blood pressure and type 2 diabetes.
I agree with sherbear. I would try the 6MP before Remicade. I was on 6MP for seven years. The first two years I took it I did enjoy remission, but then started to flare yearly, then twice a year...then always in a flare. I did try Remicade and gave Humira a shot. I had surgery at age 63. I am now 66 and feeling great!
