Just a quick comment on the Elvis Snarl. I got the same thing sometime around the one year mark and it was the first sign of hyptertonic muscles (involuntary hypertonicity) - in layman's terms, a muscle spasm in my cheek. This is something that can be worked out with facial therapy/massage. I waited another year before seeing a facial retrainer (Jackie Diels, the wonder woman) and had to work a bit harder to loosen the muscle. By the time I finally got off my hiney and took action, I had a fair amount of pain on that side of my face due to the muscle spasms. Now, however, the snarl is gone and the pain is gone. This is apparently fairly common with facial recovery. You may want to ask your doctor when you next see him if he thinks this is hypertonicity and if so, can he refer you to someone who can help you work on it.
Good luck!
