Doublevision: I was diagnosed with General Myasthenia Gravis in November of 2017. I searched for over a year until I found a Neurologist who referred me to a Neuro-muscular specialist at Weill Cornell Medical Center New York City. Blurred or double vision has been one of my symptoms that centers around how tired I am and varies from day to day. Although I had many MG symptoms it wasn't until the Neuro-muscular specialist had blood work done that checked the Acetylcholine levels in my blood. It is my experience that a General MD may not have a clue about these types of tests(There are others Now) that will confirm an MG patient in 80 to 90% of cases. I now am prescribed Pyridostigmine and Prednisone and can drive again depending on the day. Find a good Neurologist(Neuromuscular Specialist) at, Weill Cornell, NYC, Cleaveland Clinic, Duke University, Mayo Clinic, or University of Pennsylvania. God Bless you.
