Hi there, I'm also in a similar diagnostic limbo with a similar medical background (though I have what I am convinced are bulbar symptoms). I'm based in TAS and timely access to neurologists here are ridiculously hard. I'm seeing a "general" neurologist next Friday where I will be pushing for an EMG. Have you spoken to your boss about this, especially if it's affecting your work? If you're not satisfied with your neuro, I'd google a specialist with the relevant NMD/neurophysiology interests.
