I didn't have this before surgery and I notice that my legs are always on the go. Shaking them as I write this lol. My dad used to do it and annoyed me to no end and now I can't stop. Sleeping isn't much a problem for me, takes a little bit to get to sleep as now I have to toss and turn till I get comfy. But I don't usually wake up at night because of it. I can't say why it's happening but to be honest I didn't connect it with the surgery until you mentioned it.
