I was on Humira April 2010 but had to come off it in August 2010 as both of my knees would turn red and feel really hot sometimes would be sore but the heat and redness was only worrying me.
I rung up my GI nurse aswell after a blood test from my doctor was negative can't remember what for but was something to do with the muscles not he joints itself as Humira can do something to the muscles.
My GI nurse told me to come in and see the GI doctor and he said to come off humira for 1 month if it gets better then its the humira.
A year later and its still there even after stopping Humira.
