If the bloodwork all turns out negative, the EMG doesn't really show anything, but you have all of the symptoms, fit the descriptions to a "T", and mestinon works miracles against them,

Is it MG, or is there something else that mestinon also works on, or what?
Or, once all the results are in with nothing on paper to show for it, will the doctors say it's not mg and take away my miracle drug and send me out the door?
