Chiropractic care consists primarily of spinal manipulation. In spite of sales pressure and practice building techniques for which chiropractors are notorious, spinal manipulation has been around for a long time, has helped a lot of people, and is worth a try. There are large philosophical differences even within the chiropractic camp, and the care you get can vary significantly from office to office. But sometimes, nothing else will do, and chiropractic 'hits the spot'. Many Naturopaths offer spinal manipulation, and is what most Osteopaths emphasize.
A Chiropractor is licensed as a DC, a Naturopath as an ND, and an Osteopath as a DO. Some Chiropractors also have an ND degree!
