Leg Pain Nerve Block: Lumbar Sympathetic Plexus

The lumbar sympathetic plexus is a collection of nerves that carries sympathetic nervous supply to the lower extremities. The plexus lies in front of the psoas muscle at lumbar vertebral levels L2, L3, and L4. Psoas muscle is a low back muscle that helps to stabilize the spine, allows the spine to flex, and hips to rotate. We can help you manage pain by providing nerve block.
