I can give you links for seronegative Sjogrens and case histories too. Just let me know when you are ready for them. I am so sorry you are having to go thru this. I've got my fingers crossed that Mayo will give you the answers you need. Anyone with seronegative Sjogren's knows the limitations that come with small fiber sensory, axonal, and the mental fog that goes with it. How can you work when you can't remember things?
