It's been 2+ years since i have been suffering from swollen, stiff and painfull knees. All the test results for any symptoms of RA have come back inconclusive. Apart from Vit D deficiency, the doctors haven't been able to figure out, any other problem. The concern still being the same, non of the medicines administered have been effective. The swelling comes and goes, leaving me unable to walk and to daily chores. Please suggest if i need to see a specialist for this, since i have only consulted ortho till now.
