So, last Friday I was up in northern Michigan while Alison had an appointment with another neurologist. He is not related to the MSU Health System and according to my wife was very supportive and wants to actively help her get back to work. He prescribed Neurontin, which she has been taking for almost a week.
I'm happy to say that this medicine basically made our trip to NYC possible. She would not have been able to do any of this without it. It lessens her fatigued, masks most of the tingling, and generally just makes her feel more "normal". And she's only taking a small dosage right now. We're going to try to up the dose a little and see what happens.
So, although we still don't have a diagnosis, at least she has a little relief from the symptoms!
