Ganglion Impar Block

A ganglion impar block can be useful in managing pain to the rectum, genitalia, and perineum. This technique is often used in patients that have history of cancer or have undergone radiation treatment. The procedure involves the advancement of a needle into the tailbone region to inject the ganglion impar. Medications used during this injection typically include a local anesthetic and a steroid medication. The relief of the pain is temporary, but the area can be injected with longer lasting medication if there have been positive effects following the first injection.
