Thought I would post this for people who are maybe doing a search on Humira on this site. I know that it's been a life saver for many many people and that my doctor has prescribed it hundreds of time and has not seen the reaction I've had. About a week after my first loading dose (4 injections) I became very very ill. High fever, vomiting, rash, incontinence, horrible joint and muscle pain and the muscles in my right leg very weak which effects my ability to walk. I'm on steroids and one, by one, the symptoms have resolved. I'm left with the muscle weakness. I'm hoping it too will clear up. I find the inability to walk quite disturbing as I am a physically active person usually. I have to say that I am soooo grateful the joint and muscle pain has resolved. I'm not sure how I was going to lie with that level of pain.

I should note that I seem to have an immune system that is always in hyper vigilant mode. If it sniffs a hint of danger it goes into full warfare. I had serum sickness from Remicade as well but it was less severe and short lived.
