What is Degenerative Disk Disease (DDD)?
Degenerative disk disease refers to the wear and tear changes in the spine, particularly the disks. The change generally seen is disk height reduction, or thinning of the disk. The most common areas include the lumbar and cervical spine. While seen less frequently, one can have degenerative disk disease of the thoracic spine. These changes themselves could be a reason for pain, or resulting spinal canal narrowing and pinched nerves can cause pain.
