As far as going back to work, I agree with Stacey. If you have six weeks, plan on taking them. You'll be very glad you did. I'm a retired second grade teacher and was still in the classroom when I had my surgery. I had a teaching assistant, so thought I could go back half time after two weeks. I'm so glad I didn't! My class had a lot of illness going around, and my principal didn't want me to come back and get sick. I ended up staying out 6 weeks and when I went back to school, I was strong and felt fine. I'm certain I would have struggled had I gone back at 2 weeks.
In my experience, surgeons don't really know what this recovery is like. You have to go through it to understand it. I don't know how much you're lurked around the forum, but if you haven't already read it, you might want to read my early recovery journal:
Glad you've joined the forum! It's a great place to ask questions and get support from others who've been through the same recovery.
