A pudendal nerve block is a medical procedure designed to alleviate pain in the pelvic region by targeting the pudendal nerve, which provides sensation to areas such as the perineum, external genitalia, and anus. This technique is commonly employed in the diagnosis and management of chronic pelvic pain conditions, including pudendal neuralgia—a condition often resulting from nerve entrapment that leads to persistent discomfort in the pelvic area. Additionally, pudendal nerve blocks are utilized as a form of regional anesthesia during various
gynecologic, obstetric, and anorectal procedures, offering effective pain control while minimizing the need for general anesthesia.
The procedure involves the precise injection of a local anesthetic, sometimes combined with a steroid, near the pudendal nerve to interrupt pain signals and reduce inflammation. Healthcare providers may use imaging guidance, such as ultrasound or fluoroscopy, to ensure accurate needle placement. Patients typically experience temporary numbness in the targeted area, with potential side effects including discomfort at the injection site, bleeding, infection, or, in rare cases, temporary leg numbness due to the proximity of the sciatic nerve. While serious complications are uncommon, it’s essential for patients to discuss potential risks and benefits with their healthcare provider to determine if this procedure is appropriate for their specific condition.
