I continue to be under investigation for whatever ails me (coming up to 1 1/2 yrs now). Most recent consult suggested MG. All labs are negative. Symptoms are classic and are increasing. I am to start a trial of Mestinon this week. The greatest barrier to getting this diagnosis is that I have much discomfort. I have been told that pain is not really associated with MG. It is usually tolerable, but is intense (sometimes for days), after significant exertion or a lengthy road trip (which I have just returned from and am really suffering). I use Tylenol #2 for minimal relief and rarely so. Does anyone else experience pain? Thanx
