Lower Back in 1: Lumbar vertebrae (L1–L5)

Population studies suggest that a large majority of adults will experience at least one episode of low back pain during their lifetime, making it one of the most frequent reasons for clinic visits. Is bed rest recommended for low back pain? Current guidelines, including those from the American College of Physicians, generally advise against prolonged bed rest and instead recommend staying as active as tolerated.

Does a disc herniation always require surgery? Most disc herniations improve with conservative management such as exercise and time; surgery is typically reserved for cases with significant, persistent nerve compression or red-flag features. Sciatica describes pain radiating along the sciatic nerve path into the buttock and leg, usually caused by irritation of a lumbar nerve root rather than the sciatic nerve itself being diseased.

Can core exercises prevent low back pain? Trunk and hip strengthening is commonly recommended to support the lumbar spine, though research suggests general physical activity and load management play a comparably important role in prevention. Recurrence is common because contributing factors such as deconditioning, prolonged sitting, or heavy lifting mechanics often persist after the initial episode resolves.
