I started out a couple of months ago with a nodule on my little finger. I was also experiencing severe fatigue. In the last month I have had nodules appear on almost every finger, some at top joint, some on middle joints. My hands started hurting like crazy and the last week it has progressed to both wrists. It feels like glass in my wrist joints!
I went to my Foot and Ankle OS for a follow up visit (have had four foot surgeries for tendon tears). I mentioned the pain in my wrists and showed him the nodules. He ordered Sed rate, CRP, ANA, and R Factor. The sed rate and CRP were elevated, the ANA ok and RFactor negative. He has referred me to a rheumatologist
My question is: can osteoarthritis or other conditions cause these elevated numbers/symptoms or strictly RA? If RA wouldn't R Factor be positive?
