Welcome to the board!

Good to see you finally have a diagnosis, it's been a long road for you!

There are quite a few people out there who are sero-negative, my neuro says this is not as uncommon as one might think. The twitches can be looked at several ways, some people have them as a side effect to Mestinon, some have them before they takes medication.. If you Google Muscle Fasciculation you will see this is a symptom for several muscle diseases, including MG. It can also be something called Benign Fasciculation Syndrome, which is basically frequently twitching muscles.

At my house we call the mind fog "sometimers" because sometimes I can't remember what I was going to say, or do, finish a sentence! Stress and lack of rest play a large part in how MG effects your memory.

Good luck with your upcoming tests,

Rachel
