Query: Carpal Tunnel Surgery HERE I COME!!!!

After one week of using this mouse my wrist began to hurt. Upon investigating what might be the cause I realized that there is no setting to set what position you hold the mouse. If you hold the mouse at a 45 degree angle and move left to right then the cursor moves diagonally instead of left to right. Most basic mice drivers have the ability to adjust this. Second... the mouse is spastic! I have adjusted and adjusted and there is just no decent speed on the mouse. So basically you have two speeds... spastic or slow. Which may also be contributing to my newly self-diagnosed carpal tunnel syndrome.I did search on Logitech for a different driver for the mouse and was unable to find one, which then lead me here to shop for a new mouse.
