Although it’s rare, once in a while neck pain may be a warning sign of cancer, infection, autoimmune disease, or some kind of structural problem like spinal cord injury or a threat to an important blood vessel. Some of these ominous situations cause hard-to-miss signs and symptoms other than pain and are likely to be diagnosed correctly and promptly — so, if it feels serious, go get checked out. Otherwise, if you are aware of the “red flags,” you can get checked out when the time is right — and avoid excessive worry until then.

Chiropractors, especially in America, have a reputation for unnecessarily treating patients.[6] In many circumstances the focus seems to be put on economics instead of health care.[6] Sustained chiropractic care is promoted as a preventative tool, but unnecessary manipulation could possibly present a risk to patients.[4] Some chiropractors are concerned by the routine unjustified claims chiropractors have made.[4] A 2010 analysis of chiropractic websites found the majority of chiropractors and their associations made claims of effectiveness not supported by scientific evidence, while 28% of chiropractor websites advocate lower back pain care, which has some sound evidence.[197]
Chiropractors use hands-on spinal manipulation and other alternative treatments, the theory being that proper alignment of the body's musculoskeletal structure, particularly the spine, will enable the body to heal itself without surgery or medication. Manipulation is used to restore mobility to joints restricted by tissue injury caused by a traumatic event, such as falling, or repetitive stress, such as sitting without proper back support.
