Thank you again for taking the time to reply so thoughtfully and thoroughly to my post. You've definitely put my mind at ease about the twitches. Though I'm not thrilled by the possibility of an MG diagnosis, it's a lot less scary than an ALS diagnosis!

I do not get a rash in the sun. I really don't have any of the classic symptoms of lupus. I only ended up at the rheumatologist's office because I saw a neurologist for worsening migraines and he checked my ANA as part of his workup. When he saw that it was high, he referred me to a rheumy.

I did have a urinalysis done about six months ago as part of the rheumatologist's workup. At that time, everything was normal, no signs of protein.

I will give some serious thought to restarting the Plaquenil, as my rheumatologist does feel quite strongly that I should be on it.

Thanks again!
