So, is there a difference? When my sleep doc told me I may have Sicca Syndrome, I had never heard of it. When I researched it online, not much is said about Sicca, and often refers back to Sjogrens. I found this:

I have a mouth full of fillings, and now, broken teeth. I have been diagnosed with dry eyes, although my boss, also my optometrist, says it's hormonal or allergies, so I use Refresh or Systane Ultra every day. The gritty sensation in my eyes is a daily occurance. The dry throat started last year, and now that I have a CPAP machine, I am finding the dryness much worse, with my tongue stuck to the roof of my mouth every morning. Years ago, my voice changed to the deep, raspy voice I have now. I spend most of one summer with no voice at all. Dry nasal passages is a daily occurance too.

I also know there are different ways of testing for Sicca/Sjogrens, some better than others. What is the best way?

Thank you.
