weakening hands

for my right arm, my tennis elbow refused to go away since early oct 08. in fact, it has deteriorated to the point where i can hardly move my arm and fingers without feeling pain and weak, even for typing my keyboard. for my left arm, things seemed ok... at least until this afternoon in office when i noted a general weakness on my hand and that i could not use my little finger to press the `ctrl' key while stretching my thumb to press the other keys (such as `p' or `b') at the same time... the whole hand just seemed so weak...

wonder why this is so...
