What is the significance of "rheumatoid nodules?" I have a growing nodule on the outer surface of of my arm. Two doctors told me they are rheumatoid nodules, but another says they are benign tumors of the tendon sheath. They are unsightly, but I don't want to go under anesthesia to have them removed. If they are RA nodules, could they appear in any other area of my body?
