The ganglion Impar is a hub or connection site for nerves of the sympathetic nervous system, which can be involved in coccyx pain and pelvic pain. Dr. Foye summarizes and evaluates recent injection techniques used in the treatment of tailbone pain, and advocates for performing ganglion Impar nerve blocks by using approaches that can achieve nerve blockade with minimal patient risk when performed under fluoroscopic guidance.
