My father had myasthenia gravis MG in his late 70's. I am noticing some of the MG symptoms he had in myself. Saliva leaking out the corners of my mouth. Weakness in my arms. What kind of doctor treats, diagnoses, and specializes in MG? What kind of tests are there to help with diagnosis? I am at the start of my journey and hoping progress has been made since 1991 when my dad died.
