In addition, you can always go to a larger city, to perhaps a hospital in a university setting, and let them have a look at your MRI, do a repeat one to compare, and a neurosurgeon can read those
pictures just fine without a radiologst, and see what THEY say about how come you fall out like you do.
The way to look at this thing is, if the docs can come up with WHATEVER diagnosis they do, and they treat you for it, and you become well, that's the goal and all this guesswork is for naught.
