Hi! I am so glad to have found you! I also have myatonia congenita and so does my dad.
I also experience the falling and muscle weakness. My dad has had several episodes of periodic paralysis. We both have stomach problems ao that may be related to the condition.
I have knots in my neck that cause migraine-like headaches and they flare up when there is a weather change. Cool fact: I used to live just across the border from you in north Texas and, if you pay close attention to your body's signals, they will tell you when bad weather and storms are moving in!
It is very hard to find doctors who know a lot about the condition because there are not a whole lot of us that have it. I have'nt had much luck myself.
One thing you might want to do is have your kids tested because it is genetic. It is very fortunate to know your grandpa has it because my dad and I did not know our biological relatives or our family history and it took twice as long to find out what was wrong with us!
