Hey Knittens! You're in Michigan? I'm from Michigan but left many years ago. Well all the advice is right on. What I've found to be very important for me coz I get a sore wrist too... I have 3 or 4 projects going at the same time. I always have a pair of socks on small dpns. I find the afghan and vest I'm making which are on Size 11 straights, does make my wrist hurt after awhile, so I put that away for a day and just work on the smaller needles, my socks. I don't know if you make socks or work on small needles but they are much less stressful than big needles on the wrist, I've found anyhow.
Yeah, and stretching exercises for the hands and wrists. My Pilates teacher always finished the class off by having us put our arms straight up in the air and MAKE A FIST then stretch hands out, repeat, then just kind of waving our wrists around in lazy circles. Important if you knit a lot!
good luck & cheers,
