Be sure your grips are the right size. Grips that are too small for your hands will cause you to squeeze too tightly, putting too much pressure on the tendons and carpal bones in your hands. Your finger tips of your left hand should barely touch the thumb pad when you grip the club. Also be sure to hold the grip in the middle of your fingers of the right hand. This takes the pressure off the right wrist when at the top of your backswing.
