> i dont have any nerve damage (that i know of) but if i touch along my ring or little finger near the knuckle, sometimes i feel a tickling sensation on my cheek next to my ear. kinda weird!

That's funny. I think I can reproduce that.

Do you often use those knuckles to touch that area of your face? Might be that those nerves fire together so often, your brain strongly associates them. I have a habit of massaging that area of my face while thinking and slouching on my chair.
