I have been tested negative for Sjogren's. The test was taken before my peripheral neuropathy symptoms because of persistent dry eyes. I am using several eye solutions. All along I was confident that I dont have Sjogren's syndrome.

Until my neurologist casually mentioned that having a negative result does not mean that I dont actually have Sjogren's. Is this true?

I dont want to undergo the lip biopsy because of so many posts here that says how terrible the side effects are.
