I am so sorry to hear about the pain that you are experiencing. I have been on Humira for the past 3 years and I have never experienced any pain in my ribs or back. I would definitely contact your doctor a.s.a.p. and let him know what is going on. My main complaint of side effects with Humira is weight gain, dry skin and ear popping...more allergy type symptoms.
I was on Remicade too. Unfortunatley, Humira has never worked as well for me either.
Take care and keep us posted!
