Ganglion Impar Block

The ganglion impar is a part of the sympathetic nervous system that sends pain signals from the groin, tailbone and pelvic region. It is located near the coccyx, or tailbone, relaying sensation from the reproductive organs and other pelvic components. A ganglion impar block injection can interrupt pain signals and offer diagnostic and pain relief benefits. Caliber Pain™ offers ganglion impar block injections for pain management at our medical facility in New York City.

Ganglion impar block injections are performed similarly to other types of nerve block injections. A small amount of local anesthetic is combined with a steroid for the treatment. Our interventional pain physicians utilize fluoroscopy or image guided needles to perform concise delivery of the ganglion impar block.

Pelvic Pain Diagnosis and Relief

The ganglion impar block injection can have diagnostic and pain relief benefits. The local anesthetic can offer almost immediate pain relief, and this can help determine the source of pain. The anesthesia effects dissipate in a few hours, but the steroid can offer longer-lasting relief when it begins taking effect in a few days. If a ganglion impar block is effective in relieving rectal, pelvic or other localized pain, radiofrequency ablation may be considered for long-term interruption of pain signals from the ganglion impar.

Ganglion impar blocks can be performed in an outpatient procedure at our clinic in Midtown Manhattan. The procedure takes less than a half an hour, and patients will need to be monitored for 20-30 minutes after the injection for any reactions. Unless sedation is used, there is no downtime required after the treatment.

If you suffer from tailbone, pelvic, rectal or other localized pain in the groin area, a ganglion impar block may be a solution for pain management. Contact Caliber Pain™ to schedule an appointment to discuss diagnosis and pain relief options.
