I saw the chiropractor today and he told me that did a rather good job on myself. I sprained my sacro-iliac joint. According to him, that's rather difficult to do. About two weeks ago, I fell about halfway down the stairs. I caught myself some but I still landed on my butt, hard. My chiro was on vacation and he's good enough that I preferred to wait for him to come back rather than see another one. I'm going to have to wait a sacroiliac belt for the next twelve weeks. Bleh.
