For over a year ive been having pain in my arm, hands and fingers. Started in my arm as if I had fiberglass in my arm, then months later it just felt like a chemical burn on my arm. I can not stand for anything to touch my arm. Now my knuckles hurt really bad they turn red and feel like paper cuts on them and my middle finger has a vein that bulges out and burns some days more then others. My Dr is sending me to a rheumatologist to check to see if I have lupus or ra. What do y'all think?
