Ganglion Impar Blocks

A ganglion impar block is a procedure used to reduce some of the symptoms of chronic pelvic or rectal pain by blocking nerve impulses. The ganglion impar is a structure located at the level of the coccyx. Once in the procedure room, our nursing staff will position you on your stomach on a narrow table.

The ganglion impar is a collection of nerve cells next to the tailbone (coccyx) that may be involved in long-lasting pelvic or anorectal pain. By injecting numbing medicine (local anesthetic) around the nerves the cause of your pain can often be identified.
