I went off to the chiro, and he said, more or less, that my shoulder/neck was all seized up because we were working on my lower back and working on the base of things does tend to make other things move around. He thought it was good that I came in early. I did too, because I hurt quite a lot less now than I did when I went in.
The cake is made, but not finished. Much to do, still. I should go upstairs and work on it. Soon. Sooooon.
