Hi Cindylb,
Sometimes Sjogrens doesn't show up in your SSA or SSB blood work. But you still have it if you have the symptoms. The best rheumatologist that I ever went too said he diagnosed it from the symptoms as the blood work was so erratic. I don't know how to prevent lymphoma or any of the other diseases that can be a result of Sjogrens. My advice is to keep your eyes moist- I use Systane ultra and drink lots of water. It has worked for me and my eye doc had told me to use it. I did find that if you get a flare- give in to it- rest as much as possible. Since I have started doing that, my flares are now hours- not days.
Take care,
Joan
