I am sorry to hear how some of the last two weeks has gone for you and Andy. The Duke part sounded like they took good care of you. It sounds like Duke is the place to sort through highly complex situations like your. At least you have a firm answer instead of this back and forth blaming this and that.
Holy wow on that Mega EMG you got there. I am sure they did as much as necessary to ensure their diagnosis is accurate. OUCH!
Take it easy, rest and We hope you feel better soon.
