psoriatic arthritis
"When I started taking Humira in 2008, I was covered over 80% of my body. Took Humira, and it was at least 8  weeks (if not more) for any improvement on the plaque psoriasis, although I noticed big improvement in arthritis pain and stiffness.

Once it cleared, within 2 years it was again widespread. Finally I have been on it regularly for two years in addition to Methotrexate (without it I feel it in my knees and hands).  I now only have no more than 5 spots here and there. 

Very happy with it, and only side effect was 1 time liver function affected, but easily fixed with lesser dose of Methotrexate."
