Neither did I and neither did any doctor/specialist I ever met.

Mine is much much better this week and again is fluctuating perfectly in tandem with all the other muscle weakness that I have.

In one way I am glad it is part of the package I already have and not a brand new separate issue.

For a long time I thought I was starting to develop some sort of a superior canal dehiscence syndrome:

Goodness! Imagine hearing your eyeballs moving whilst reading!

(The lady I recently read about with that disease had about as much success with her diagnosis as someone with atypical MG )

I´m not really sure but I´m guessing the pathological erosion of bone in this disorder would result in progressive rather than fluctuating hyperacusis and auditory distortion.
