LUMBAR SYMPATHETIC BLOCK
A lumbar sympathetic block is an injection of medication that helps relieve lower back or leg pain (sciatica). It can be used to treat:
- Vascular insufficiency
- Peripheral neuropathy
- Reflex sympathetic dystrophy
- Complex regional pain syndrome
- Herpes zoster infection (shingles) involving the legs
Sympathetic nerves are located on both sides of your spine, in your lower back. A steroid medication and local anesthetic injected into or around your sympathetic nerves can help reduce pain in that area.
