Synnove,

If you have tested positive for RA, then Sjogren's be considered 'secondary'. It doesn't always appear on labs, but you can still have the condition. There is a 'process' to get an appointment. The information is below:

Read the bio on Dr. Birnbaum at the "Meet our Team" link on the right.

You should definitely asked for the Schirmer's test to be done. It can gauge the level of dryness/tear production in your eyes. It's a bit uncomfortable for a few minutes, but not that bad.
