Also hoping SOMETHING definitive comes out of all of that testing. (Though if they say "well, you definitely have autoimmune neuropathic complications of Sjogren's syndrome", or something to that effect, it's not much of an advance.

Gear up for a battle with your insurance company, though--insurers these days balk at anything that's pricey, no matter how much you might benefit, and no matter how many supporting papers Liza Jane may send.)
