My wife had the surgery two years ago on both hands at the same time. Happened over thanksgiving break at school (she's a teacher). I remember because I had to cook dinner for 18 people. Not a big deal, but I usually cook on the grill. Anyway, I asked her what advice she'd give, and that was to do the therapy your dr's recommend, take it easy otherwise, and give it time to heal. She came back with more grip than she'd had for years before the surgery. With in about 6 months, you couldn't tell there had ever been anything wrong, and you have to really look to even find the scars.
Good luck with it, and take it easy.
