Hi Topsie, I also have palatal myoclonus. It was diagnosed by nasoendoscopy as palatal and pharyngeal myoclonus.

I believe I also have it in the larynx and oesophagus (it spasms on its own).
The myoclonus was clearly visible on vidoefluroscopy (done to check for dysphagia)...which I also have to some degree on the right side.

My palatal myoclonus is clearly visible whether mouth opened or closed (twitching constant in throat etc).

Over a period of years if these get bad, I've gotten major cramps R side facial and R throat/neck area. It burns and cramps and I'm out laying on my left side with ice flannel towels applied to these areas.

I believe that that the oesophageal-stomach junction cramps/spasms and burns with the pain going right thru to the back.

It is so difficult when I move my arms it makes the palatal & other myoclonus worse.

What are you taking for it? How was it caused?

cheers
