I play so much poker and so many tables I am starting to have some numbness in my wrist.  It is a slight pain and effects my gameplay.  I play around 6-7 tables simultaneously for hours and need to solve this.

I know it sounds pretty stupid, but I make a real good living off of playing many tables at once.  However typing out many commands day after day, second after second is starting to pain my wrist.  Anyone else experience this problem?  How can I fix this?  None of the sites I play at allow software like table ninja.
