With my first surgery, at my follow-up appointment a little over a week later, I was released to exercise as long as I wasn't lifting weights. I went to my women-only bootcamp class (http://www.beautyhunters.org/
) two weeks after surgery. I'd been feeling fine at that point, but when I started exercising, my scar got SO itchy. Not just kind of itchy as a sign that it's healing, but so unbearably itchy that I wanted to claw my skin off. This time I said I would wait three weeks before I started exercising again, but my doctor took my Synthroid away at about the two week mark, so....yeah, I haven't exercised in over a month.
This is to say I don't really have any advice, except that I think you should go on walks and otherwise take it easy for a couple of more weeks, and then you will be able to go back to your regular exercise routine.
