Psoriatic Arthritis
"My psoriatic arthritis started about 36 months ago I tried light therapy and was on enbroe for about 8 months with limited improvement from either treatment procedure.
My back, head, and legs were very covered with psoriasis and were extremely itchy. My scratching exacerbated  the problem and I had bleeding scores all over my legs. 
One year ago I went on otezla and within 4 months my back and head were completely clear and my legs were vastly improved
I did not experience any side effects to speak of although I did lose 10 lbs.
Currently my legs are about 80% clear however after about 5 months of use the palms of my hands and my feet were severely infected with psoriasis to the point were they were cracking and bleeding no matter how much l tried to look after them"
