Driving
That's a question for your surgeon. Mine approved me at my first postop visit, which happened to be just shy of two weeks. A lot depends on how one's postop recovery is going, what med(s) one might be taking postop, and other factors.
Like others said, you should check with your doctor. Mine told me as long as I wasn't on pain meds, and could stop without hesitation (no pain) it would be fine. If you're in pain at all, or will be hindered to make a quick stop because of pain I wouldn't try it, it wouldn't be safe for you, or others.

Mine advised until my post-op visit but I didn't wait that long. I didn't take any pain meds, except the day of surgery, but I didn't feel ready to drive until about 5 days after surgery. I needed to be able to get in enough calories to feel normal, and I needed not to be tired. Once I felt truly clear headed I was willing to get behind the wheel. I don't think I rushed it, but I'm not sure my surgeon would agree.
