Okay, quit wondering and tell your doctor!
This is exactly why it's so frustrating when I hear someone has not been definitively diagnosed and then something else pops up. Do you really need Imuran if you have something that's not autoimmune?
I can't remember if you have MDA clinics in Canada. Can you see someone who is an expert at this to at least rule it out? It would make me crazy if I didn't know for sure - and I didn't for years - what disease I had. I'm classic MG, though.
Well, crap. I hope you will talk this over with at least your neuro, if not primary doctor. You never had antibodies but had a positive SFEMG, right? Or is my mind completely gone?
