Why does my Thumb bother me when I tap the space bar on the computer keyboard?
 
By constantly tapping the space bar with your thumb you are stressing the tendons of the thumb which could cause De Quervain`s Disease.  Every hour you should switch the thumb you use to tap the space bar, allowing the tendons time to rest. For further information please read our section on De Quervain`s Disease
