The nerve that numbs your fingers starts in your neck

The nerve that runs into your thumb, index and middle finger doesn't begin at your wrist. It's built from nerve roots that leave your spine in your neck, then travel down your arm to your fingertips. Think of it as one long line: the Nerve Line.
Squeeze that line anywhere along the way and your body reports it in the same place: the fingers at the end. Your hand is just where the static shows up. It isn't always where it starts.
