Thanks. I had the SFEMG first thing this morning that came back negative, no evidence of an issue despite all the symptoms (including droopy eye & soprano, wispy voice changes during the appointment). The doctor said he's not saying I don't have MG or LEMS, just that he couldn't tell from today's test so he can't provide a diagnosis. He wants me to see an ENT doctor and maybe a GI doctor.
So far, my employer has denied an accommodation request for work off the phone. Today, I adjusted the request to see if the accommodation could be granted cutting hours to part-time. Stress levels would be much reduced if I had the short-term disability (I'm readying to submit appeal paperwork.)
Although other throat symptoms continue, on the plus side, the feeling of being actively strangled has gone away and I no longer feel the need for oxygen.
