I agree with you all-- I believe this is a positive step towards a dx but is not definitive. I am negative to the blood test Achr(sp). I am going to visit my sis for a month and have a follow-up with rhuemy and nuero upon my return--then I believe we will move forward with tests etc., til then I will continue to take mestinon. I'm also concerned that I take plaquenil and metroprolol which are contraindicated with mg. Does this mean they are not as effective or inert or exacerbate the mg? I also was taken magnesium supplements because I heard they can make your mg symptoms worse. When you have flares of mg what are your symptoms--mine were severe jaw ache-neck pain body aches eye pain severe weakness --before I only would have eye pain. I have felt very fortunate during this last year I never have pain. Thank you all for responding--I appreciate all advice! I am so ignorant to mg and trying my best to be informed..... Thanks so much!
