I dont have MG, but I do have MS. I just wanted to hug you Having any long term, unknowable disease stinks!

Keep a journal. This way you can point back to specific days and say "see the pic" this is what my eye does. and the MD can see if for himself. then if you went to the ER, he can see the reports on that day.

There are a handful of diseases that are catch alls. Once they get to the bottom of the barrel and cant explain it, they are left with a dozen or so and have to pick the one that best fits what symptoms you are showing. Helping them by clearing documenting what happens when you are not in front of them will help.

Then, do your part. Eat healthy, get some exercise. Sit in the sun for 15 mins a day and get vit d. Take a multi vit. practice yoga and meditation.

Then come back here and get loads of hugs
