The spinal nerves are the electrical wires of the body. They originate at the spinal cord and exit the spinal column through the intervetebral foramen. Nerves exiting the area of the lumbar spine provide sensation and motor control to the back, buttocks, legs and down to the foot. Damage or interference with the transfer of information of these nerves can cause neurological problems such as pain, weakness, abnormal sensations, numbness and changes in spinal reflexes. These symptoms may occur in the back, leg and down to the foot.
