CPS can be from dumb habits as well. Had a friend who brought it on
himself by his habit of hitting a wrench with the palm of his hand to
break a tight bolt. Repeated blows to the right area is what did his.
I've got CTS as well but just live with the numbness. When I feel it
coming on, I stop and move my fingers around and things get better

and you can get the numb hands symptom from other reasons. i had it, and the
problem turned out to be a ruptured disk in the top part of my neck, with
bone impinging on the spinal column.
