“The conventional wisdom is that herniated discs are responsible for low back pain, and that sacroiliac joints do not move significantly and do not cause low back pain or dysfunction. The ironic reality may well be that sacroiliac joint dysfunction is the major cause of low back pain, as well as the primary factor causing disc space degeneration and ultimate herniation of disc material.” Joseph Shaw, MD, Orthopedic surgeon, Topeka
Most pain results from stimulation of nerve endings called nociceptors. These tiny sensory receptors are present in joint structures, spinal ligaments, intervertebral discs, and the muscles that move them as well as well as the blood vessels surrounding the spinal nerves. Twisting, stretching, crushing or tearing may stimulate nociceptors as chemical waste products accumulate due to mechanical stresses in soft and osseous tissues. Any number or all of these conditions may be operative in the spinal, pelvic, or sacroiliac region at any one time. Small wonder there are so many different, often conflicting, diagnoses and treatments for low back pain.
