I got the photos of my spine and pelvis from my chiropractor today. He has a very cool in-office file systems in which the x-rays are made into jpgs.
You can see that my spine is actually crookedy because my right leg is shorter than the other. The lines drawn on the pelvis x-ray are the level lines where my hips should actually be going. Apparently, this is the case for most people! Who knew? (Probably other chiropractors.)
There is also a problem with my lowest vertebra. It's tilted backwards or forwards or something, but you can't really see it in these pictures. That is actually the thing that has been giving me all the trouble, however.
