I'm 56
No exotic drugs (!) and no strange food.
No strange activies either - I was on the phone when it happened and just continued as normal for another 10 minutes or so until the call ended naturally
At the moment (nearly 48 hours since the event) everything still works and nothing has dropped further than it's gradually been doing over the last 20 years. There is still slightly reduced sensation and tingling in the left side of the lips, teeth and tongue, as well as the L thumb.
Thinking back - some years ago I had a severe pain in the L side of my face (around the eye and including the lips, teeth and tongue) which became a reduced sensation and tingling before fading naturally after a couple of weeks or so - various tests were done but no problem was found. Many years ago I had long-term problems with a tingling right pinkie and thumb but this was put down to a slight calcium outgrowth on one of the vertebra in the neck touching the spinal column - the tingling went away by itself.
