Hi. My symptoms started with droopy eyes and double vision after a minor forehead concussion playing with daughter when she was 2 years old. That was 17 years ago. At the time I visited several specialist and sud-specialist with no diagnosis (almost 2 years). After educating myself I asked a neurologist to prescribe Pyridostigmine (Mestinon) to see how my eyes would react. After couple of days my eyes were going back to almost normal. Since then I started the same medication and prednisone to control symptoms under MG experienced Neurologist. It started ocular MG and then became generalized after 4 years. I never tested positive for musk antibodies. I was diagnosed based on the symptoms; droopy eyes, double vision, difficulty swallowing, weakness throughout my whole body, shortness of breath, falling,... All those symptoms and severity would come and go depending level of physical and emotional stress, There are more things that I can say but will leave that for later as needed. Good luck!
