I've been fighting wrist pain for a while, mostly when i'm having to drive more than an hour and a half a day; I recommend 3 exercises from here, DynaFlex spining ball , power Web rubber net and wrist curl bar, AKA wrist roller. Gave substantial relief after using 3-4x/week for 3 weeks.
Also, in your other daily activities, make sure you keep your hand in line with wrist, i.e. top of hand in line with top of forearm, center of forearm in line with middle finger. It's easy to cock your wrist at acute angles when you're driving, riding a bike, using power tools etc, without noticing.
