I saw Dr. M.L., the orthopedist. The X-ray technician at the office took X-rays. Dr. M.L. said that I had joint damage from arthritis, and that six of my vertebrae were floating loose from my ribs on one side, and five on the other. The impression I got were that things were crooked back there. I'll get a cortisone shot on Monday and start physical therapy on Thursday.
I was playing phone tag with L.M. for a while, but we finally got in touch this evening.
