Lumbar Sympathetic Block


 

Injection needles will be positioned and then there are three main ways to produce the block: injection of a long acting local anesthetic to produce a diagnostic block to safely see if your pain can be treated this way; injection of a neurolytic substance such as phenol or alcohol to destroy the lumbar sympathetic nerves; and the use of radiofrequency energy to similarly destroy the nerves in a highly controlled way.
