Abstract

Low back pain is a distinctly different condition from lumbar radicular pain (sometimes called “sciatica”). Radicular pain is lancinating pain that travels into the lower limb along a narrow band [1]. It is caused by disc herniation, foraminal stenosis, lateral recess stenosis, or other space-occupying lesions in the vertebral canal that compromise lumbosacral nerve roots. In contrast, low back is dull, aching pain that is centered on the lumbar, or lumbosacral, spine but may radiate into the buttocks or proximal thigh; it can radiate beyond the knee but not typically so. Its causes are elusive and difficult to determine.
