rheumatoid arthritis
"Like some RA people, diagnosed easily back in 1990. Genetically "gifted" it from maternal side. 
Having tried all the old first line drugs w/o success I started on second line of meds including Enbrel. It was great for 6 months. Then it stopped. Remicade was started & after one infusion I had a horrible reaction: Serum Sickness" . Paralyzed for 3 days, severe allodynia (pain all over). Would never take this drug. It was the mouse protein in Remicade that I reacted to. Wish you all well!"
