A lumbar sympathetic injection is a procedure designed to relieve pain in the lower back, legs, or feet, particularly from conditions like complex regional pain syndrome (CRPS) or neuropathic pain. This is a sympathetic nerve block that targets the autonomic nervous system, which can contribute to chronic pain, vascular pain, or excessive sweating.

The injection is administered in the lower back, with X-ray or ultrasound guidance ensuring precise placement near the targeted nerve group.

This treatment may reduce chronic leg or foot pain and improve symptoms related to nerve and blood flow disorders. If this injection does not provide enough relief, other options include medications, physical therapy, spinal cord stimulation (SCS), peripheral nerve stimulation (PNS), or dorsal root ganglion (DRG) stimulation, depending on the pain source and type.

Risks are low but may include bleeding, infection, or nerve irritation. Temporary soreness, numbness, or hip pain may occur. Before the procedure, inform your doctor if you take blood thinners, have allergies, or are pregnant. Fasting may be required if sedation is needed, and you should arrange for someone to drive you home.

Some patients experience immediate relief, while others may need multiple injections for full effect. Avoid driving or strenuous activities for a day, and follow up with your provider team to assess progress and determine next steps.
