Lumbosacral plexopathy is a peripheral nerve problem that results from an injury to the lumbar or sacral plexuses located in the lower part of the vertebral column. The injury can result from diabetes, tumor, radiation, and obstetrical injury.
Symptoms include pain, numbness, tingling, weakness, or hypersensitivity and can depend on the underlying cause of the injury.
