cyclelops,

That's what I've been thinking and why I decided to go back to my first impression and reason I sought a neurology consult in the first place.

After all testing came back negative, except for skin punch biopsy and thyroid, along came the clinical Dx of Sjogren's by PCP, cardio, rheumy.

But after reading the abstract by the CC neuro who did my SPB and the one that Navy posted, find myself leaning toward SFSN causing sicca but can't be sure until after I hear what this new neuro has to say.

SFN can even cause the face flushing, dry face, dry lips, dry nose, dry mouth, dry eyes, red or white or both areas of skin. What I've got is all there.
What I don't got is so many things that Sjogren's folks have.
