I am not confirmed diagnosis, but LEMS is top on the list... but before I crashed 3 years ago, I couldn't hold a spoon, grip the steering wheel, hold my babies... or a crayon/pencil... it was horrible... frustrating... and no one knew what was going on with me... About 4 days after My IVIG loading dose, I picked up a crayon and could color with my kids again.. I cried..
