Just an update. The doctor ordered blood work to test for MG. I go back in a couple of weeks for the results.

I had a single droopy eye for a long time that got droopier when I was tired. My legs would go out from under me when I'd get almost down the stairs going to my back yard.
Getting off the zero turn mower and stepping off onto the ground, I fell on my face on several occasions.
Chalked it all up to old age, out of shape, etc.
Eventually diagnosed with LEMS.

I noticed the folds in my eyelids were different.. I noticed after getting out of a hot shower and attempting to put on eye shadow..I had just had a baby, so i too, thought i was just tired.. and then it got worse, so i thought, well maybe thyroid eye issues (that's common with post partum after all)... then after showers I was having trouble even standing up afterwards.. carrying my kids.. finally holding silverware, flipping switches, breathing.. and my face looked awful (like skin melting off of my skull- the pics still freak me out)! Good times
