A 2006 systematic cost-effectiveness review found that the reported cost-effectiveness of spinal manipulation in the United Kingdom compared favorably with other treatments for back pain, but that reports were based on data from clinical trials without sham controls and that the specific cost-effectiveness of the treatment (as opposed to non-specific effects) remains uncertain. A 2005 American systematic review of economic evaluations of conservative treatments for low back pain found that significant quality problems in available studies meant that definite conclusions could not be drawn about the most cost-effective intervention. The cost-effectiveness of maintenance chiropractic care is unknown.
Neck pain can also be associated with headache, facial pain, shoulder pain, and arm numbness or tingling (upper extremity paresthesias). These associated symptoms are often a result of nerves becoming pinched in the neck. Depending on the condition, sometimes neck pain is accompanied by upper back and/or lower back pain, as is common in inflammation of the spine from ankylosing spondylitis.
