Sounds like you've done all you can...and why did he call DH? Isn't that illegal to divulge a patients history/results to anyone but the patient? Unless you agreed to this.....
Guess it just goes right back to the PCP....or a new Neuro. I'd say you are still in limbo and have to get a second opinion. Maybe when you reach my age you'll have more showing up? Not that mine are giving me answers....but I have more showing now than I did then
I'm about out of here for my (drumroll) results.....
EDIT: If you asked him directly about thos results....he must have had an answer?
