The back is improved - I managed to pop my hip back into place again. The first time I did this I thought the popping might have been a coincidence, but it was definite this time - I wiggled around, my hip made a loud popping noise, and I was suddenly able to walk without a cane again.

I really need to get this looked at - losing the ability to walk four days after I go dancing is decidedly sub-optimal.

In other news, when they say Lord of the Fries is a "quick game", they lie, a lot. I doubt I will ever play more than one hand of that game, and you're meant to play a number of hands equal to the number of players.
