The success rate of chiropractic adjustments varies with factors such as the condition, and the severity of said condition or injury. With that being said, chiropractic care has shown to be largely successful at treating musculoskeletal conditions in the form of back and neck pain as well as headaches. The majority of people who receive forms of chiropractic care self-report it as effective, and in addition, the majority of people are satisfied with the care they receive. Furthermore, the chances of serious complications from a chiropractic adjustment are very slim, and often the worst side effects seen are mild soreness and stiffness that lasts for a short period of time.
