BTW, if you go to the Mayo Clinic, and they say you have Sjogren's, the insurance will totally back off. When I told the person who was negotiating a settlement with me that, btw, I have an entire mayo chart documenting my illness, I could almost feel his stomach hit the floor.

They know they cannot bring a court case against Mayo. No jury will believe their hired hands against the Mayo Clinic chart. It's a very strong negotiating point.

So, if you can make the trip there, and need to establish the diagnosis, it may well be worth it.
