There are many possible signs of spinal cord trouble in the neck,8 with or without neck pain, mostly affecting the limbs in surprisingly vague ways that can have other causes: poor hand coordination; weakness, “heavy” feelings, and atrophy; diffuse numbness; shooting pains in the limbs (especially when bending the head forward); an awkward gait. Sometimes people have both neck pain and more remote symptoms without realizing they are related.

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.[161] 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.[162] The cost-effectiveness of maintenance chiropractic care is unknown.[12]


Mainstream health care and governmental organizations such as the World Health Organization consider chiropractic to be complementary and alternative medicine (CAM);[1] and a 2008 study reported that 31% of surveyed chiropractors categorized chiropractic as CAM, 27% as integrated medicine, and 12% as mainstream medicine.[56] Many chiropractors believe they are primary care providers,[4][21] including US[57] and UK chiropractors,[58] but the length, breadth, and depth of chiropractic clinical training do not support the requirements to be considered primary care providers,[2] so their role on primary care is limited and disputed.[2][21]
Most people believe that chiropractors treat back pain. That is a true, but there is so much more that chiropractic care can achieve. Because chiropractors help to remove pressure from the nervous system, they can also influence many other conditions. It is common to hear chiropractic patients say that they came in for back pain and their headaches got better.
Among people seeking back pain relief alternatives, most choose chiropractic treatment. About 22 million Americans visit chiropractors annually. Of these, 7.7 million, or 35%, are seeking relief from back pain from various causes, including accidents, sports injuries, and muscle strains. Other complaints include pain in the neck, arms, and legs, and headaches.
