[[is it possible to have a neg.
RA test yet still have
RA?]] Yes, certainly - a good rheumatologist will know this
and treat you for it anyway.
[[I have always been under the understanding that RA is a small joint issue.]] No, it can affect any joint in the body, anywhere there is cartilage, including the ribs, pelvis, spine, jaw, small bones of the ear, etc. Also, inflammation can affect your eyes and other tissues as well. RA certainly is NOT limited to certain joints.
