Chiropractic is a form of alternative medicine. A chiropractor is a person who went to school to learn chiropractic. Chiropractors may diagnose and treat many conditions relating to muscles, joints, and nerves of the body. They may give what is called an "adjustment" to the body. An adjustment is a fast short push to an area of the patient's spine or other joints to help their condition. Chiropractors do not use drugs to treat patients. They use natural treatments such as nutrition, exercise, physical therapy, adjustments, and massage in order to help their patients.
