Nerves are part of a complex network that begins in the brain and works its way down the spinal column, eventually exiting through more than 60 different locations near the top of the lower back. This complex system can become damaged in the spinal column, as well as other bony structures such as wrists, hip, knees, ankles, and shoulders, in numerous ways.
"Compressive neuropathy" is the general term for nerve disorders in the spine. These occur when the nerves in the spine are compressed and cause the exiting nerves to become trapped and swollen. This causes a pain that radiates from the buttocks and can range all the way down to your toes.
Mild cases of nerve damage result in numbness or weakness, but severe cases can lead to fatigue, stabbing pain, loss of motor control, or even, in extreme cases, paralysis. Permanently damaged nerves in the spine can leas to blurred vision or headaches, loss of hearing, slurred speech, bowel and bladder problems, and other symptoms.
