Hi, my name is Skyler and thanks for letting me join this forum. Over the years I've seen a number of neurologists, but my disease appears to be hard to diagnose. The doctors suspect myasthenia gravis or a congenital myasthenic syndrome. My blood work came back negative twice and my single fiber EMG was also normal in 2011. My muscle weakness not only affects my legs and arms but also my breathing, chewing and swallowing. My lung function is deteriorating. So far no hard diagnosis, so no treatment. That's my story!
