I got that one morning...no previous symptoms. Two of my schoolmates had just died from sudden strokes...and I was at the 'magic age'.
Called young wife at her work (her youth won't let her retire for 14 more years!) She had me do the arms-out-in-front test, etc. All the 'over-the-phone' tests.
Went to the Dr's office, by now I couldn't wink nor smile...left side. She said Bell's palsy. Took me 3 months to kick it, (she said 6 weeks tops, but she's a young thing, and cannot leave her...Whoops!)
That's another thing: now my mind wanders.
Get well soon. Just exercise your facial muscles much as possible. (I smiled a lot and resumed playing my Alto sax.)
That was early last year, and my left eye still feels a little swollen...but it's just the nerve endings. I still look fabulous! My wife fibs to me...
