Fanfaire,
Your diagnosis of sero-negative Sjogren's should be a snap to get at Mayo Clinic. I was diagnosed with sero-negative Sjogren's and sero-negative spondylarthropathy as well, by Dr. Michelle Mauerman and the doctors she referred me to within the Mayo Clinic in Rochester, Minn.

There is also a Mayo in Arizona. Dr. Mauerman may be able to refer you to someone at that branch.
