Thanks for the comments, guys - Yes, I'm following up both with further testing (an EEG and another MRI) and with a neurologist. No, my doc didn't have the specifics of what some of those results could mean for me particularly. More wait and see. By now, I"m good at it.
In other news, it's THURSDAY and that means The Office. Which is new tonight. Must now go watch genius! You should watch it, people. Always.
