I have Sjogren’s and often it is mid-diagnosed as fibromyalgia. Not sure if they tested you for Sjogren’s.

I was diagnosed with a blood test but not all Sjogren’s patients test the same.

ANA (Anti-nuclear antibodies)- Positive in 50-70 % of Sjogren’s. ANA is positive in many other CTDs (5, 6, 9). Some healthy people carry ANA, although often at lower titers (6). Infections, liver disease, and other conditions may also be associated with a positive ANA test.

Check out the website for more information. It was created by an md with Sjogren’s. Another great site is smart patients. See:

I wish you luck finding a diagnosis. If you do have Sjogren’s, the first line drug of defense against further damage is hydroxychloroquine. It takes a while to work but significantly helps many of the symptoms of Sjogren’s.
