I'll give another pro-Humira experience
. I was anemic for 15 some odd years. Even iron infusions didn't restore my ferritin levels. After a couple of months on Humira, my hemoglobin and ferritin levels shot up well into normal range. I also no longer have abdominal and back pain. If I recall correctly, it took up to a couple months for me to really see results.
Some people complain of joint pain while on Humira, but I've been lucky enough to avoid that potential side effect.
