rheumatoid arthritis
"I had been on Remicade for many years with no side effects at all, perhaps a little tired every once in a while, but nothing serious.  My doctor and I questioned whether I had rheumatoid arthritis. Then all of a sudden the Remicade stopped working and bam I had 2 flares that were unbelievable before doc could get anything to work for me.  I was heart broken because it was such a good medicine for me."
