My shoulder hurts if I use the mouse for more than 30 minutes at a time, that's why I currently only play games with an xbox 360 gamepad.
However, with Diablo 3 I will not be able to do that.
Does anyone know of an alternate input method that has similar precision to a mouse? I've been thinking about using a Wiimote, but I don't think its accurate enough. Maybe a PS Move?

You might still consider mice, as there are Trackball mice which are similar to normal mouse precision but operate in a different way:
This for example is the "Logitech M570 Trackball". Basically instead of moving the mouse on your table you move the Trackball with your thumb. Your shoulder does not move a bit.
There was once a top professional Counter Strike player that used a similar mouse, but I forgot his name, which proves that you can make it work even in precision games that require fast reflexes. Here is an old discussion about this topic: Gamespot Thread
This does not really concern your question, but I guess you are using your mouse in a wrong way. Day[9], a professional Starcraft veteran has a 1 hour show that explains how to correctly use your mouse and keyboard for Starcraft 2. You can easily adapt this to Diablo 3 or any computer game. Check it out: Day9 Daily 252.
There are a million options, but I consider most novelties. As others point out, ergonomics are probably the core of your issue. Since thumbs seem to work better for you then wrist movements, one option to consider is a trackball mouse like the Logitech 570 I've linked below. There is a definite learning curve for using them, and I think they'll never be "FPS" precision or speed, but I've played with folks that converted and used them effectively in games like Starcraft and Diablo.
