Quote - What is it about the tingling that artists might find debilitating, I wonder? Is Carpal Tunnel Syndrome painful or just annoying? I recommend the use of a laser mouse that can send your cursor to any side of your screen with a mere twitch of the hand. You don't even need to move your wrist.

 

Yes, it can develop to the point that it will cause actual pain.  Just for the record, while the pain is felt in the wrist, it is actually repetative movements of the fingers that cause it.  The "tunnels" are guides for the tendons that run from the muscles in the forearm that control the finger movements.  So it's actually the pushing of the buttons that is the  biggest problem.
