I have chronic neck pain especially on the right for over a year. I have been to general doctor,chiropractor,orthopedic doctor and 8 weeks physical therapy. Working diagnosis is a muscle strain. Nothing seems to help! I' was at dentist couple weeks ago and he took some X-rays of lower teeth and found a periapical abscess on my lower right canine. This tooth had had a root canal about 10 years ago. I have appointment with endodontist next week for retreatment and if that doesnt work out then an apicoectomy. Im fine with this work but do you think it's possible that it is the cause of this ongoing neck pain? It's extremely bothersome.
