How much time off
Dr. K wanted me off at least 4 weeks, preferably 6. I went back to my desk job after 3 and I was fine. Really tired the first week or so of having to get caught up after the time off, but I napped at lunch everyday and I think that helped.
I did find that I had to get up and walk around for a few minutes every hour or so. My insides felt like they were getting squished if I sat for too long, started getting achy.
