Ah the facial EMG. Fun stuff.... I found it awkward but funny at the same time when I got it done. I had it in my hand, then upper arm, then face. It was able to prove that I did have MG in my face, where my blood was still coming up negative.

I'm sorry it wasn't the result you were looking for. I know how you feel, I was very relieved when it showed on mine and my doctor said right to me as he was doing it, "yup, it's showing abnormal, you have myasthenia". Especially after it didn't show in my blood, and when other tests (like for thyroid, etc) were all coming up negative also.
