Chronic pain is the most common cause of long-term disability. It lasts longer than "normal healing" (several months), and can cause severe problems.
Lumbar radiculopathy is a condition caused by the compression and/or irritation of a spinal nerve root in the low back. It may be caused by the herniation of an intervertebral disc from is normal position in the cervical spine.
Typical symptoms include radicular pain, also called sciatica, which consists of pain that travels along the back of the thigh and sometimes into the calf and foot.
