Rheumy agrees I have symptoms of sjogrens and I asked her re 40% of people being sero negative but she said she would never diagonose without a positive blood test.
I have no reason for the dry eyes not on any drugs etc that cause it.
I am in the UK so the early sjgrens test not available here either.

I was convinced it is sjogrens but at the moment I am getting no joy anywhere
Seeing my neuro on Monday so will se where I get with him.
