Lumbar degenerative disk disease occurs when the disks in your lumbar spine wear down. The reduced space between the vertebrae may pinch spinal nerves, causing back pain.

What Is Low Back Pain? The low back, also called the lumbar region, is the area of the back that starts below the ribcage. Almost everyone has low back pain at some point in life.
The lumbar spine connects with the thoracic spine above at the thoracolumbar junction and the sacral spine below at the lumbosacral joint. The lumbar motion segments may be affected by congenital (birth-related), degenerative, traumatic, or inflammatory disorders.
The lumbar portion of the spine bears the most body weight and also provides the most flexibility, a combination that makes it susceptible to injury and wear and tear over time.
The spine extends from the skull to the coccyx and includes the cervical, thoracic, lumbar, and sacral regions. The lumbar spine consists of 5 moveable vertebrae (numbered L1-L5). The lumbar vertebrae, as a group, produce a lordotic curve [1]
