JavaJay,
I don't really know how the Humira feels since I am not the one doing it. But I wanted to let you know that my 16 year old son is on Humira. He uses the pen since he did not want to see the needle, and it's so easy. He does the injections in his thighs, not his stomach, and he has never once complained to me about the pain. I just wanted to send you a little note of encouragement
Best of luck with your decision. I know it's not easy.
Take care,
Nancy (son Ben,16,CD dx 3/06; Humira, Milk Thistle, Probiotic)
