Pudendal Nerve Block
A pudendal nerve block is a targeted injection placed near the pudendal nerve. It may be used to help diagnose or temporarily reduce selected pelvic nerve pain. The injection may include local anesthetic, with or without corticosteroid when clinically appropriate.
At Manhattan Pain Medicine (MPM), pudendal nerve block NYC care begins with diagnosis-first evaluation. The goal is to determine whether the pudendal nerve is likely contributing to symptoms and whether a block may provide diagnostic information, temporary relief, or both.
What the Pudendal Nerve Does
The pudendal nerve carries sensation from parts of the perineum, external genital region, and rectal area. It is also connected to pelvic floor function. When the pudendal nerve is irritated, compressed, inflamed, or sensitized, symptoms may include burning, stabbing, electric, raw, pressure-like, genital, rectal, or perineal pain. Pain may worsen with sitting and improve with standing or lying down in some patients.
These symptoms can be distressing and difficult to explain. They may also overlap with pelvic floor dysfunction, pelvic dystonia, endometriosis, bladder pain, bowel symptoms, hip or SI joint mechanics, spine-related referral, scar tissue, trauma, central sensitization, or PGAD-related sensory symptoms.
Diagnostic vs. Therapeutic Pudendal Nerve Blocks
A pudendal nerve block may be diagnostic, therapeutic, or both. A diagnostic block helps answer whether the pudendal nerve is contributing to the pain. If the patient has temporary relief in the expected area after the injection, the response may support pudendal nerve involvement.
A therapeutic block may provide symptom reduction for a period of time. Relief may last hours, days, or longer, depending on the medication used and the patient’s condition. Some patients may not respond. MPM reviews the response carefully because the result may guide future treatment decisions.
Pudendal Nerve Blocks for Pudendal Neuralgia
Pudendal neuralgia is a condition in which the pudendal nerve is believed to contribute to pelvic, genital, rectal, or perineal pain. Pain may be worse with sitting and may feel burning, stabbing, electric, or hypersensitive. A pudendal nerve block may be considered as part of the diagnostic and treatment process when symptoms match the nerve territory.
A block does not cure pudendal neuralgia. It may help clarify whether the nerve is involved and may provide temporary relief. Persistent symptoms often require a broader plan that may include pelvic floor therapy, medication management, pain psychology, nerve hydrodissection, peripheral nerve stimulation, neuromodulation, or specialist coordination.
Pelvic Floor Dysfunction, PGAD, and Pelvic Pain Overlap
Many patients with suspected pudendal nerve pain also have pelvic floor dysfunction, pelvic dystonia, PGAD-related symptoms, endometriosis overlap, urinary or bowel symptoms, or medical trauma from years of unexplained pain. These factors can influence both symptoms and treatment response.
A pudendal nerve block may be considered when nerve involvement is suspected, but it should not replace evaluation of other pelvic pain contributors. MPM’s approach is to map the symptoms, identify overlapping drivers, and build a coordinated plan rather than treating the pudendal nerve as the only possible source.
Ultrasound Guidance and Procedure Planning
Ultrasound guidance may be used for selected pudendal nerve blocks when it supports anatomical precision and safety. The procedure plan depends on the patient’s anatomy, symptoms, suspected target, and clinical goals. Before the injection, MPM reviews the expected benefits, limits, risks, alternatives, and what to monitor afterward.
After the block, patients may feel numbness, warmth, heaviness, soreness, temporary pelvic sensation changes, or a brief pain flare. MPM reviews the degree and location of relief, how long it lasted, and whether the response matches the expected pudendal nerve distribution.
What the Response May Mean
If a pudendal nerve block provides meaningful temporary relief, it may suggest that the pudendal nerve is contributing to the pain. This may guide next steps such as pelvic floor therapy, nerve hydrodissection, peripheral nerve stimulation, medication management, pain psychology, or neuromodulation.
If the block does not help, it does not mean the pain is not real. It may mean the pudendal nerve is not the main pain generator, the target needs reassessment, or another condition is contributing. MPM may then evaluate other pelvic nerves, pelvic floor muscles, spine-related pain, hip or SI joint mechanics, gynecologic or urologic issues, or central pain mechanisms.
Risks and Urgent Symptoms
Risks may include pain flare, bruising, bleeding, infection, allergic reaction, temporary numbness or weakness, urinary or bowel changes, nerve irritation, vascular injury, local anesthetic toxicity, steroid-related side effects when steroids are used, incomplete relief, temporary relief only, or no relief.
Patients should seek urgent evaluation for fever, spreading redness, severe swelling, new weakness, new numbness, inability to urinate, new bowel or bladder dysfunction, saddle anesthesia, severe pelvic or abdominal pain, heavy bleeding, pregnancy-related pain, blood in urine or stool, severe allergic reaction, or rapidly worsening symptoms.
For selected patients, a pudendal nerve block may be an important step in understanding pelvic nerve pain. MPM’s role is to determine whether the pudendal nerve is the right target and how the block fits within a coordinated, medically responsible pelvic pain plan.
