Rethinking Pain from Lumbar Disk Herniation
Lumbar disk herniation occurs when one of the cushioning disks between the bones in the lower back becomes damaged, allowing the soft inner material to push outward. A disk herniation itself may not cause symptoms, and studies show that many adults have positive findings on MRI without pain. However, when a herniated disk irritates nearby nerves, it can lead to localized low back pain and/or symptoms like sharp, shooting pain into the leg. Traditionally, pain and disability related to lumbar disk herniation have been attributed primarily to nerve compression. However, more recent research suggests a more complex picture—one in which the nervous system, including the brain, plays an important role in ongoing pain.
