I actually did some work at home after about a week, and then went back properly after three. But I was still quite slugglish moving around and would get stabs of pain from time to time, so I wouldn't have been able to do anything physical.
How do you get there? You're not going to be wanting to be running for a bus or train, and they told me not to drive for a month, though I did after 2 weeks and felt okay.
