I would definitely say there is something autoimmune going on. Other than the titer, what was the pattern (speckled, homogenous/diffuse, centromere, nucleolar)??

As for your dry mouth/eyes during these flares. These can be present with neuropathy, but of course most common with Sjogren's. I'm curious about your lip biopsy...what was the exact result/report? Did they mention ANY acinar damage, inflammation, and/or ANY lymphocytes?? What score did it receive?

Do you have any arthritis/joint pain? Have you been assessed for joint fluid (associated with inflammatory arthritis), like psoriatic arthritis?

I assume you have seen a rheumy. What do they think is going on?
