Christopher,
I wish you the best with your upcoming evaluation at Mayo. Not having a diagnosis, when clearly there is something going on is not good for the mind, body, and soul.

I traveled to Mayo earlier this year and was pleased with my evaluation. My antibody tests have been negative, as well as my SFEMG. However, my Tensilon test was positive. I was told that ocular MG has a lower rate of positive tests, including SFEMG. What a relief for me to hear that! I had totally been dismissed in the past by a neuroophthalmologist b/c of my neg SFEMG, altho he admitted that clinically it looked like MG.

Keep us posted.
