Personal Training Tip-

The wrist.  The ankle.  Small joints that even the most body-conscious of us tend to overlook.  Yet if these joints are compromised or impaired, they can be just as painful and immobilizing as a knee, shoulder or hip injury.  The most common wrist injuries are tendonitis of the extensor tendons and carpal tunnel syndrome-both overuse injuries resulting mostly from our repetitive motions in the realm of electronic gadgetry.  In carpal tunnel syndrome, the median nerve gets compressed from tissue swelling and causes pain to radiate into the fingers, as well as weakness and numbing. 
To help prevent carpal tunnel syndrome, I recommend that you avoid keeping your wrist in an extended position, which causes all its muscles and tendons to work harder.  Keep your wrist in a neutral position with your forearm straight, so the wrist isn't bent backwards.  Try a cushioned pad for the computer mouse and see how it feels, it might take time to get used to but it beats the long term damages of doing nothing.
