Hi, I have a question concerning rheumatoid arthritis. I am getting ready to start Humira injections, and I mainly deal with pain in my feet and ankles, my wrists, my fingers (feels like I have cramps in my fingers, and I have to shake it out), and it runs up my arm(s) (burning pain)into my neck and shoulders… both sides, but predominately in my left side...but it's not pain in all areas every day... sometimes I'm not bothered by one area, but it's flaring up in other areas, sometimes it's all areas period. Does rheumatoid always affect the same joints day in and day out, or is this normal, for it to sporadically affect different joints, different days?
