at the computer, you know you want to make sure the top of your wrist is flat, not bent back at all?

Also, if you use a mouse, if you are right-handed, move the mouse to the left of the computer, and use your left middle finger to right-click, and your left index finger to left-click - you don't have to alter the meaning of the mouse buttons. this way you are using the strong middle finger, not the sore index finger which I think the nerve runs thru the inside of the wrist.

be careful while sleeping not to bend your wrists, maybe wear supports.

don't carry heavy stuff for a while, like laundry soap and giant bleach bottles, that's what does it to me, carrying them with just a couple of fingers thru the handle.
