About chiropractors
NCCIH says chiropractors often treat problems related to the musculoskeletal system. It says their manual methods range from stretching and sustained pressure to specific joint manipulations, usually delivered by hand as a quick and gentle thrust. It says the purpose of the manipulations is to improve joint motion and function, and that they are most commonly done on the spine. Cleveland Clinic lists lower back pain, neck pain, muscle pain and headaches among the most common reasons for a chiropractic adjustment. It says you may feel tired or sore afterwards and some people might get mild headaches, and that these side effects are temporary. In rare cases, it says, chiropractic care may cause serious complications such as herniated disks, cauda equina syndrome (pinched nerves in the lower spine) or stroke.
