I just read your post which sounded vary similar to the symptoms I am having caused from an auto accident. I do not have facial pain but my shoulder, arm and hand are painful with numbness in the hand. I was told this is a pinched nerve at the c-6 to c-7 vertabra. I also had a bone chip removed from that area causing some of the problem. Did your chiro take any x-ray's? If not, you may want to get some, they may show the cause of your pain. I had to get a second cat scan to revial my problems. I don't want to scare you, but the more you know, the better off you'll feel. Steevo
