Everything I read says a small percentage of people with MG can have negative bloodwork and EMG/SFEMG. I have the symptoms. Was diagnosed by a neuro in the hosp. using Tensilon. My problem is I guess he is the only neuro around that got that memo:) No one will treat me with he other neg. results. Even though I have had 4 crisis and intubated once. I was brought out of the crisis each time with the standard treatment. I am also on Mestinon and CellCept. I need help, PLEASE.
