I have been having problems with jaw fatigue for several weeks now. My lower jaw feels like it just wants to lay on my chest most of the time. It feels very tired most of the time and if I chew too much it will always cause a migraine. (I have chronic migraine disease)

Does anyone else feel that way when having problems with their facial muscles?

I have a tentative DX of MG from the neuro-optho I went to but still don't have a definitive DX. The doc has ordered a SFEMG of the eye and facial muscles which I have scheduled for next week. I go back to see him on Sept. 30th will get an actual DX then, I guess. He did mention that even if it is not a definitive DX that he would probably go ahead and put me on Mestinon and prednisone as he feels that is what I have.

During the exam, which took hours, or at least seems like it did, he and the intern as well as the 4th year med student that he had there (this is Kansas University Med Center, a teaching hospital) all saw the same symptoms of MG and all seemed to be in agreement.

I still don't have any ptosis, thankfully, but I definitely have convergence issues as well as other stuff I can't remember now.

Well, I guess now that I have rambled, I'll get back to my original question about the jaw fatigue. Can others describe what it feels like to them? I am trying to decide if it is MG or the migraines, as I always have facial pain and discomfort with the migraine.

Thanks,
Shannon
