Carpal tunnel may be handed down

Don't be so quick to blame your aching wrist on the long hours spent on the computer.

Carpal tunnel syndrome is a weakness or pain felt in the wrist when the nerve that runs from the arm into the hand is squeezed.

Harvard Medical School researchers believe the syndrome may have more to do with genetics than being at a computer for long periods of time.

After reviewing more than 115 studies on the condition they found hereditary factors were more prevalent than cases of frequently using the hands.
