Ganglion of Impar Injection
The ganglion impar is a cluster of nerve cells in front of the joint between the sacrum (lowest part of the spine) and the coccyx (tailbone). Nerves from some parts of the lower pelvis and groin pass through this ganglion, including nerves from the lower part of the rectum, anal region, the lower part of the urethra, vagina and vulva, scrotum, and tailbone.
This ganglion of impar injection procedure is used to reduce the symptoms of chronic pelvic pain or rectal pain by blocking nerve impulses. Although uncommon, risks include bleeding, infection, nerve injury and allergic reaction to the medication.
