Had a dose of this some years ago.Almost complete recovery in six weeks, completely normal in 2 - 3 months. Keep the muscles working: grin, yawn, say things like lollipop and apple pie. Be careful you don't chew the inside of your cheek when eating.

My consultant was quite laid back about it, and said like yours that the treatments might help (or might not).

Apparently it has been called 'Lorry drivers palsy' since one of the triggers is thought to be prolonged draught on the facial nerves.

It's unlikely to happen twice I was told.

Good luck
