Right now my head is ringing, as if someone hit a switch, or I got boarded by Probie again.
Just above the right eye on the forehead. It comes and goes and lasts for 5 minutes or however long it takes for the spy plane to fly over.
It's winding down now. If it were just me, I wouldn't be as concerned, but the Mrs hears and feels it also at the same time.
I've been a right side sleeper ever since a outdoor brawl at "The Penalty Box" @ Fraser Hockeyland in 1980. It was tough driving a 4 speed Mousestang with my left shoulder dislocated.
Over the last 2 weeks the ringing has started, so it's probably not because of my sleep position
