I had similar a number of years ago. Did 2 things: 1) left handed mouse. Found I needed to switch the buttons for my brain to work with it. Took a few days to get used to it. Now I can switch back and forth without effort. 2) Wrist support. My wrists were hurting too. So I used a bowling wrist support and that reduced the total motion at the wrist level.
