What is the difference between a chiropractor and an upper cervical chiropractor?
Nothing.
Its like asking what the difference is between a womens doctor and a middle-of-the-road doctor. They both have alike training, but one has chosen to channell adjectives of their patients to one type.
The Cervicle Chiropractor has like peas in a pod training as the normal Chiropractor, but have chosen to limit their business to looking at the cervicle region. I enjoy no idea why they would do this. Maybe it's so that those think they hold more training in the nouns or something.
I would prefer to go to a mundane Chiropractor as they would probably assess your body as a whole to some extent than just looking at your lead and neck.
Actually a total lot of nothing.
Sounds similar to someone wants a title that sounds more far-reaching.
