Re: Negative tests, so what is it?
You can have seronegative rheumatoid arthritis...a quick search on the internet will be helpful (A major (and relieving) difference which medical studies have observed is that patients with seronegative RA have comparably less joint erosion and destruction than patients having seropositive RA. Also the tendency for developing rheumatoid nodules under the skin is less in this disease than the positive population. Moreover, though the other symptoms are same as in the positive group, their severity is less, which too is a bit relieving).
Get familiar with other symptoms of RA that you could be having that would help your rheumatologist make a diagnosis; which he can even if you’re seronegative. Bilateral joint pain, swollen joints, morning stiffness and fatigue are some of the markers that are used to diagnose RA.
