Re: Facial pain/numbness
I've never had my face go numb. (Except for one time when I was getting a TrP injection and the doctor accidently anesthesized the C3 spinal nerve, but that's another story.)
Oh, one interesting point of anatomy is that the skin on a lot of your head is actually innervated from the spinal nerves, not the cranial nerves. So facial numbness actually can come from the back of the neck.
My hands go numb so often I don't even think about it anymore. On very rare occasions, it gets bad enough that I drop things instead of holding them properly. It always goes away with a few hours of patience, rest, and stretching.
