Pelvic Pain
This article was medically reviewed and approved by Dr. Zach Cohen.
Pelvic pain is a common condition that affects both men and women but is more prevalent in women due to reproductive anatomy. It refers to pain occurring in the lowest part of the abdomen and pelvis. The sensation can range from mild and intermittent discomfort to severe and chronic pain that significantly impacts daily activities.
Pelvic pain may arise from various causes, including issues related to the reproductive, urinary, digestive, or musculoskeletal systems. It can be acute, lasting a few hours or days, or chronic, persisting for six months or longer. Understanding the underlying causes and addressing them is vital for effective treatment and improving quality of life.

Treatment of Superior and Inferior Hypogastric Plexus Blocks for Pelvic Pain
Pelvic pain is a complex and often debilitating condition that can significantly impact a person’s quality of life. It can result from various underlying causes, including endometriosis, interstitial cystitis, chronic prostatitis, and pelvic organ diseases. Treatment options for chronic pelvic pain (CPP) are often multidisciplinary, involving medications, physical therapy, and surgical interventions. However, when conservative treatments fail, nerve blocks such as superior and inferior hypogastric plexus (SHP and IHP) blocks have gained attention as an effective means of managing pelvic pain, particularly when pain is centralized in the pelvic region.
Several studies have highlighted the effectiveness of SHP and IHP blocks in reducing pelvic pain and improving quality of life. Key research findings include:
- A 2017 study published in the Journal of Pain Research demonstrated that patients with refractory pelvic pain, including those with endometriosis, saw significant pain relief after receiving SHP and IHP blocks. In this randomized controlled trial, 70% of participants reported pain reduction of at least 50%, and many experienced lasting effects up to 6 months post-procedure.
- A 2020 study in Regional Anesthesia and Pain Medicine focused on the use of SHP and IHP blocks in patients with chronic pelvic pain not responding to conventional therapies. Results indicated that nerve blocks led to an average pain score reduction of 4 points on a 10-point scale, with approximately 60% of participants showing sustained pain relief for up to 3 months after the procedure.
- Another study from The American Journal of Obstetrics and Gynecology (2018) examined the long-term effects of SHP and IHP blocks in patients with severe pelvic pain secondary to interstitial cystitis. The results showed a notable reduction in both pain scores and the need for additional interventions like opioid use.
These studies underline the potential for SHP and IHP blocks to provide significant relief for patients with chronic pelvic pain.
Mechanism of Action for Pain Relief
The superior and inferior hypogastric plexuses are major nerve centers that innervate the pelvic organs, including the uterus, bladder, and rectum. The SHP is located in the abdomen near the aorta, while the IHP is found within the pelvis near the sacral promontory. These plexuses are responsible for transmitting pain signals from the pelvic organs to the brain.
When a block is performed, local anesthetics or neurolytic agents are injected into or around these plexuses, interrupting the transmission of pain signals. The anesthetic temporarily prevents the nerves from relaying sensations of pain, providing relief. Neurolysis, which involves injecting an agent that damages the nerve fibers, can provide longer-lasting relief by permanently inhibiting pain transmission.
Medical Necessity – Indications for Procedure
SHP and IHP blocks are indicated for patients suffering from chronic pelvic pain, particularly when the pain is refractory to other treatments such as medication, physical therapy, and surgery. Some common indications for the procedure include:
- Endometriosis: Chronic pelvic pain due to endometriosis, particularly when it becomes resistant to other forms of treatment.
- Interstitial Cystitis: Chronic bladder pain and discomfort that does not respond to first-line treatments.
- Chronic Prostatitis: Long-standing pelvic pain in men often associated with prostatitis.
- Pelvic Organ Prolapse: Pain from conditions like uterine or bladder prolapse.
- Chronic Post-surgical Pain: Pain following pelvic surgeries that has become persistent.
This procedure is typically considered when conservative measures fail and the patient’s pain significantly impacts their quality of life.
Description of Procedure
The SHP and IHP block procedure is performed under fluoroscopic or CT guidance to ensure precise placement of the needle. The patient is positioned comfortably, often lying on their back, and the skin is sterilized.
- For the SHP block, a needle is inserted through the abdominal wall and advanced toward the area of the superior hypogastric plexus, just anterior to the aorta. Local anesthetic or neurolytic agent is injected to block nerve transmission.
- For the IHP block, the needle is inserted through the pelvic region, targeting the inferior hypogastric plexus, located near the sacral promontory. A similar injection is made to alleviate pain.
The entire procedure usually takes about 30 minutes, and patients are monitored for any immediate complications.
Post-op Instructions and Recovery
Post-procedure care is crucial for ensuring the best outcome and minimizing risks. Patients should follow these instructions:
- Rest and avoid strenuous activities for the first 24-48 hours to allow for healing.
- Hydration: Patients should drink plenty of fluids, as the anesthesia may cause temporary dryness in the mouth.
- Pain Management: Mild discomfort at the injection site may occur, which can usually be managed with over-the-counter pain relief.
- Follow-up Care: A follow-up appointment is typically scheduled within one week to assess the effectiveness of the block and address any complications.
Most patients can resume normal activities after 1-2 days, but full recovery and symptom relief may take up to 1-2 weeks. If neurolysis was performed, the effects may last longer, sometimes months or even years.
Prognosis
The prognosis following SHP and IHP blocks varies based on the patient’s underlying condition and the success of the procedure. Many patients experience significant pain relief, with some seeing improvements for several months or even years, particularly if neurolytic agents are used. For others, the benefits may be temporary, necessitating repeat procedures or adjunct treatments.
In general, these blocks can greatly enhance the quality of life for individuals with chronic pelvic pain by reducing reliance on medications and improving overall pelvic function. However, they may not be suitable for all patients, particularly those with certain underlying conditions like infections or malignancies in the pelvic region.
In summary, superior and inferior hypogastric plexus blocks are an effective intervention for managing chronic pelvic pain, with a solid body of research supporting their benefits. These procedures provide an option for patients who have not found relief through traditional treatments, improving quality of life and reducing the need for invasive surgeries.
Radiofrequency Ablation (RFA) for Pelvic Pain
Pelvic pain, often chronic, is a complex and debilitating condition that affects both men and women. It can arise from various sources, including gynecological, urological, gastrointestinal, and musculoskeletal conditions. For many patients with chronic pelvic pain (CPP), conventional treatments such as medications, physical therapy, and surgery may provide limited relief. In recent years, radiofrequency ablation (RFA) has emerged as an effective treatment modality, particularly for individuals with refractory pelvic pain. RFA is a minimally invasive procedure that uses heat to target and disrupt nerve pathways responsible for transmitting pain signals.
Numerous studies have investigated the efficacy of RFA in managing chronic pelvic pain, with promising results:
- A 2019 study published in The Journal of Pain Research examined the use of RFA for patients with chronic pelvic pain caused by endometriosis and other gynecological conditions. The study demonstrated that 65% of patients reported significant pain relief, with many experiencing sustained benefits for up to 12 months following the procedure. The results also showed a reduction in opioid use among patients post-procedure.
- A 2020 study in Regional Anesthesia and Pain Medicine explored RFA’s effectiveness for patients with chronic prostatitis and pelvic floor dysfunction. The study found that RFA led to a 50-70% reduction in pain levels in the majority of participants, and these benefits were maintained for at least 6 months. Additionally, patients experienced improved quality of life and a decrease in the need for other pain management interventions.
- In a 2018 study published in The American Journal of Obstetrics and Gynecology, RFA was shown to reduce pelvic pain in patients with interstitial cystitis. More than half of the patients reported a significant decrease in pain, and many achieved pain relief that lasted for several months after the procedure. The study highlighted RFA’s potential as a long-term solution for patients with persistent pelvic pain who had not responded to traditional treatments.
These studies underscore the growing body of evidence supporting RFA as a viable and effective option for managing chronic pelvic pain.
Mechanism of Action for Pain Relief
RFA works by using heat to target specific nerves that transmit pain signals from the pelvic organs to the brain. The procedure involves the insertion of a needle-like electrode into the targeted area, where radiofrequency energy is applied to generate heat. This heat causes a lesion to form on the nerve, disrupting its ability to transmit pain signals. In some cases, the nerve may be permanently damaged, providing long-lasting pain relief. RFA is typically performed under imaging guidance, such as fluoroscopy or ultrasound, to ensure precise targeting of the nerve.
RFA is particularly effective for treating pain related to the following nerve structures:
- Pelvic Nerves: These nerves transmit pain signals from the uterus, bladder, and rectum.
- Hypogastric Plexus: A network of nerves responsible for transmitting sensations from the lower abdomen and pelvis.
- Pudendal Nerve: A major nerve that supplies sensation to the pelvic floor and genital areas.
By targeting and disrupting these pathways, RFA can offer significant relief from chronic pelvic pain.
Medical Necessity – Indications for Procedure
RFA is indicated for patients with chronic pelvic pain that is not responsive to conservative treatments like medications, physical therapy, or nerve blocks. Some specific conditions for which RFA may be indicated include:
- Endometriosis: When endometriosis-related pain is severe and resistant to other forms of treatment.
- Chronic Prostatitis: For men suffering from persistent pelvic pain due to prostatitis.
- Interstitial Cystitis: For patients with bladder pain syndrome that has not responded to first-line treatments.
- Pelvic Organ Prolapse: Pain from conditions such as uterine or bladder prolapse.
- Chronic Post-surgical Pain: Persistent pain following pelvic surgeries, such as hysterectomy or prostatectomy.
- Pudendal Neuralgia: Pain caused by irritation or damage to the pudendal nerve.
The procedure is considered when pain significantly affects a patient’s quality of life and other treatments have been ineffective or are not viable.
Description of Procedure
RFA is a minimally invasive procedure performed under local anesthesia and imaging guidance, such as fluoroscopy or ultrasound, to ensure precision. The procedure generally follows these steps:
- Preparation: The patient is positioned comfortably, typically lying on their back. Local anesthesia is administered to numb the area where the needle will be inserted.
- Needle Insertion: A thin, needle-like electrode is inserted through the skin, guided by imaging to the target nerve or nerve bundle.
- Radiofrequency Energy Application: Once the needle is in position, radiofrequency energy is passed through the electrode to heat the targeted nerve. This heat disrupts the nerve’s ability to transmit pain signals.
- Post-procedure Care: The needle is removed, and the patient is monitored for any immediate complications.
The procedure typically lasts between 30-60 minutes, depending on the complexity of the case. It is usually done on an outpatient basis, meaning patients can go home the same day.
Post-op Instructions and Recovery
Following the RFA procedure, patients may experience mild discomfort at the injection site, but this generally resolves within a few days. Key post-procedure instructions include:
- Rest: Patients are advised to rest for 24-48 hours and avoid strenuous activities.
- Pain Management: Over-the-counter pain relievers, such as acetaminophen or ibuprofen, can help manage any post-procedural discomfort.
- Monitor for Side Effects: Patients should watch for signs of infection at the injection site or unusual pain. If these occur, medical attention should be sought.
- Follow-up Appointments: A follow-up visit is typically scheduled within one to two weeks to assess the effectiveness of the procedure and monitor recovery.
Most patients are able to return to normal activities within a few days, though complete pain relief may take several days or weeks to manifest. For some patients, additional procedures may be necessary if pain relief is not sustained.
Prognosis
The prognosis for patients undergoing RFA for pelvic pain is generally positive, with many experiencing significant and lasting pain relief. Pain reduction can range from 50-80%, depending on the underlying cause and the precision of the procedure. For patients with conditions like endometriosis or interstitial cystitis, RFA can significantly reduce pain and improve quality of life, often with fewer side effects than traditional pain management methods such as narcotics.
However, the duration of pain relief can vary. Some patients may experience long-term relief, while others may require additional procedures after several months or years. The need for repeat procedures depends on the nature of the pain and the nerves treated.
In summary, radiofrequency ablation offers a promising and minimally invasive treatment for chronic pelvic pain, particularly in cases where other treatments have failed. With the potential for significant pain relief and improved quality of life, RFA is increasingly becoming a go-to option for patients dealing with persistent and debilitating pelvic pain.
Bilateral Sacral S2 or S3 Transforaminal Epidural Steroid Injections (TFESI) for Pelvic Pain
Pelvic pain is a common and multifaceted condition that can significantly disrupt a patient’s quality of life. It can arise from various etiologies, including musculoskeletal, urological, gynecological, and gastrointestinal disorders. Chronic pelvic pain (CPP) often persists despite conventional treatments such as medications, physical therapy, and nerve blocks. Among newer intervention strategies, bilateral sacral S2 or S3 transforaminal epidural steroid injections (TFESI) have gained attention for their potential to manage pain related to the lower back and pelvic region, especially in cases of pelvic organ dysfunction or nerve irritation. TFESI targets specific nerves that transmit pain signals from the pelvis, providing effective pain relief for many patients.
A growing body of research supports the use of bilateral sacral S2 or S3 TFESI for pelvic pain. Some of the notable studies include:
- A 2016 study published in The Clinical Journal of Pain evaluated the use of transforaminal epidural steroid injections for patients with chronic pelvic pain, particularly in cases of sacral nerve irritation. The study found that 75% of participants experienced significant pain relief, with a reduction in pain scores of more than 50%. Most patients reported improved mobility and fewer symptoms of pelvic discomfort.
- **A 2018 study in Pain Medicine explored the effects of TFESI on patients with pelvic pain from conditions such as interstitial cystitis and pelvic organ prolapse. Results indicated that the procedure was associated with significant pain reduction and improvement in pelvic floor function. Approximately 65% of participants reported sustained pain relief for up to 6 months following the procedure.
- In a 2020 study published in Regional Anesthesia and Pain Medicine, researchers analyzed the impact of bilateral sacral TFESI on patients with chronic lower back and pelvic pain. The findings suggested that patients who received the injections experienced a notable reduction in both localized and referred pelvic pain. Many patients experienced long-term benefits, with 60% reporting a significant improvement in their quality of life for up to 12 months.
These studies provide strong evidence supporting the effectiveness of bilateral sacral S2 or S3 TFESI in managing pelvic pain and improving patient outcomes.
Mechanism of Action for Pain Relief
Transforaminal epidural steroid injections (TFESI) involve the delivery of corticosteroids directly to the epidural space near the affected nerves. The sacral nerves, including those at the S2 and S3 levels, innervate the pelvic organs and pelvic floor, transmitting pain signals from the bladder, uterus, rectum, and other pelvic structures to the brain.
The TFESI procedure targets the specific nerve roots at the S2 or S3 level, which are associated with the pelvic region. The corticosteroids injected into the epidural space reduce inflammation around these nerve roots and disrupt pain transmission. By alleviating the inflammation and irritation of these nerves, TFESI can provide significant pain relief, often within a few days of the procedure. The steroid medication also helps to diminish swelling and irritation, leading to a reduction in pelvic pain.
Medical Necessity – Indications for Procedure
Bilateral sacral S2 or S3 TFESI is indicated for patients suffering from chronic pelvic pain that is not adequately managed through conservative treatments such as medications or physical therapy. Specific indications for TFESI include:
- Chronic Pelvic Pain: Pain arising from pelvic organ dysfunction, including bladder, uterine, or rectal pain.
- Pelvic Organ Prolapse: Pain related to the displacement of pelvic organs that causes discomfort and pressure.
- Interstitial Cystitis: A chronic condition causing bladder pain, urgency, and frequency.
- Chronic Prostatitis: Pelvic pain due to prostatitis that does not respond to antibiotics or other treatments.
- Pudendal Neuralgia: Pain caused by irritation or compression of the pudendal nerve.
- Post-surgical Pain: Persistent pelvic pain following procedures such as hysterectomy, prostatectomy, or other pelvic surgeries.
- Pelvic Floor Dysfunction: Dysfunction of the pelvic floor muscles leading to chronic pain and discomfort.
The procedure is considered when the pelvic pain significantly affects a patient’s quality of life and other treatments have not provided adequate relief.
Description of Procedure
Bilateral sacral S2 or S3 TFESI is typically performed under fluoroscopic (X-ray) guidance to ensure precise placement of the needle and minimize the risk of complications. The procedure involves the following steps:
- Preparation: The patient is positioned comfortably, usually lying on their stomach. The area is sterilized, and local anesthesia is administered to numb the skin and tissues around the injection site.
- Needle Insertion: A thin needle is carefully inserted through the skin, guided by fluoroscopy, and advanced to the targeted area around the sacral nerve roots at the S2 or S3 levels.
- Injection: Once the needle is correctly positioned, a small amount of corticosteroid and anesthetic is injected into the epidural space, near the sacral nerve roots. This delivers the medication to reduce inflammation and block pain transmission.
- Post-injection Care: The needle is removed, and the patient is monitored for any immediate adverse reactions or complications.
The procedure typically takes between 15 to 30 minutes and is performed on an outpatient basis. Most patients can go home the same day after the procedure.
Post-op Instructions and Recovery
Following bilateral sacral S2 or S3 TFESI, patients may experience mild soreness at the injection site. Post-operative instructions include:
- Rest: Patients are advised to rest for the first 24-48 hours after the procedure to allow the medication to take effect.
- Pain Management: Mild discomfort or soreness can be managed with over-the-counter pain relievers such as acetaminophen or ibuprofen.
- Avoid Strenuous Activity: Patients should refrain from heavy lifting or strenuous exercise for at least one week following the injection to avoid irritation of the injection site.
- Hydration: Drinking plenty of fluids helps reduce the risk of complications such as headaches or dizziness.
- Follow-up: A follow-up visit is typically scheduled within one to two weeks to evaluate the effectiveness of the injection and determine if additional treatments are necessary.
Most patients can return to normal activities within a few days, although pain relief may take up to one week to become noticeable. The effects of the corticosteroids can last anywhere from several weeks to several months, depending on the individual.
Prognosis
The prognosis following bilateral sacral S2 or S3 TFESI is generally positive, with many patients experiencing significant pain relief and improved function. Studies suggest that 50-75% of patients report a reduction in pelvic pain by at least 50%, with some patients enjoying relief for several months following the procedure.
However, the duration of pain relief can vary. While some patients experience long-term benefits, others may require repeat injections after several months. TFESI is particularly effective for managing inflammation and nerve-related pain, but it may not be a permanent solution for all patients, especially those with progressive or worsening underlying conditions.
In summary, bilateral sacral S2 or S3 TFESI is an effective and minimally invasive option for managing chronic pelvic pain, especially in cases where conservative treatments have failed. With a strong track record of success, this procedure provides patients with significant relief, improved quality of life, and a reduction in the need for opioid medications or more invasive interventions.
Ilioinguinal, Iliohypogastric, and Genitofemoral Nerve Block for Pelvic Pain
Pelvic pain is a widespread condition that can significantly impact a patient’s quality of life. It can result from a variety of underlying causes, including gynecological, urological, musculoskeletal, and gastrointestinal disorders. When pelvic pain becomes chronic or resistant to traditional treatments, nerve blocks can offer a promising alternative. The ilioinguinal, iliohypogastric, and genitofemoral nerves are responsible for transmitting sensory information from the pelvic region to the brain. These nerves supply sensation to areas such as the lower abdomen, groin, and external genitalia. A nerve block targeting these nerves can effectively reduce pain by interrupting pain signals from these regions, making it a useful tool for managing chronic pelvic pain.
Several studies have examined the effectiveness of ilioinguinal, iliohypogastric, and genitofemoral nerve blocks in managing pelvic pain. Key studies include:
- A 2018 study in The Clinical Journal of Pain evaluated the efficacy of a combined ilioinguinal and iliohypogastric nerve block for patients with chronic pelvic pain due to post-surgical complications. The study found that 70% of participants experienced a significant reduction in pain, with many experiencing lasting relief for up to 6 months. The procedure also reduced the need for additional analgesic medications.
- A 2019 study in Pain Medicine focused on the use of genitofemoral nerve blocks for patients with post-hernia surgery pain and pelvic floor dysfunction. This study demonstrated that targeting the genitofemoral nerve provided effective pain relief in up to 80% of patients, especially those with groin pain and discomfort radiating to the genital area. The pain relief was sustained for several months in a majority of participants.
- A 2021 study in Regional Anesthesia and Pain Medicine assessed the outcomes of ilioinguinal and iliohypogastric nerve blocks in patients with chronic interstitial cystitis and other urological pain syndromes. The results showed a 60-75% improvement in pain levels, with participants reporting a notable improvement in urinary frequency and urgency, indicating that nerve blocks could address both pain and functional issues in the pelvic region.
These studies underscore the growing body of evidence supporting the use of these nerve blocks for managing pelvic pain, particularly when other treatments have proven ineffective.
Mechanism of Action for Pain Relief
The ilioinguinal, iliohypogastric, and genitofemoral nerves are responsible for providing sensory innervation to the lower abdomen, groin, and external genitalia. Pain originating from pelvic organs such as the bladder, uterus, or prostate can be transmitted through these nerves to the brain.
- The Ilioinguinal and Iliohypogastric Nerves: These nerves arise from the lower lumbar spine (L1 and L2) and provide sensation to the lower abdomen, groin, and upper thigh. They also play a role in the sensation of pain related to pelvic organ dysfunction.
- The Genitofemoral Nerve: This nerve arises from the L1 and L2 spinal nerves and provides sensory innervation to the genital area, groin, and upper thigh.
When a nerve block is performed, local anesthetic or neurolytic agents are injected near these nerves, interrupting their ability to transmit pain signals. This block prevents pain from being relayed from the pelvic region to the brain, resulting in effective pain relief. The analgesic effect can be temporary or longer-lasting, depending on the type of medication used.
Medical Necessity – Indications for Procedure
The ilioinguinal, iliohypogastric, and genitofemoral nerve blocks are indicated for patients experiencing chronic pelvic pain that is not responsive to conservative treatments. Specific indications for these nerve blocks include:
- Post-Surgical Pain: Persistent pain following abdominal or pelvic surgeries, including cesarean section, hernia repair, or hysterectomy.
- Pelvic Organ Dysfunction: Pain associated with conditions like interstitial cystitis, endometriosis, or pelvic floor dysfunction.
- Chronic Groin Pain: Pain in the groin area that may be due to nerve compression or irritation.
- Genital or Inguinal Pain: Pain in the genital region or inguinal area that does not respond to other treatments.
- Pelvic Nerve Irritation: Irritation of nerves that supply the pelvic organs, leading to chronic pain or discomfort.
The procedure is considered when the pain significantly affects a patient’s quality of life and other interventions, such as medications, physical therapy, or nerve blocks, have failed to provide relief.
Description of Procedure
The ilioinguinal, iliohypogastric, and genitofemoral nerve block is a relatively simple and minimally invasive procedure, typically performed under fluoroscopic or ultrasound guidance to ensure precise needle placement. The procedure generally follows these steps:
- Preparation: The patient is positioned comfortably, often lying on their back. The area to be injected is sterilized, and local anesthesia is administered to numb the skin.
- Needle Insertion: A fine needle is inserted through the skin and advanced toward the targeted nerve regions, usually near the inguinal ligament or just above the pelvic rim. Imaging guidance helps ensure accuracy.
- Injection: Once the needle reaches the appropriate location, a small amount of local anesthetic (and occasionally corticosteroid) is injected around the ilioinguinal, iliohypogastric, or genitofemoral nerves.
- Post-injection Care: After the injection, the needle is removed, and the patient is monitored for any immediate side effects or complications.
The procedure typically lasts 15-30 minutes and is done on an outpatient basis. Most patients can go home the same day.
Post-op Instructions and Recovery
Following the nerve block, patients may experience temporary soreness at the injection site. Post-operative instructions include:
- Rest and Observation: Patients should rest for 24 hours following the procedure, as the anesthetic takes effect. They should also refrain from heavy lifting or strenuous activities.
- Pain Management: Mild discomfort or soreness at the injection site can be managed with over-the-counter pain relievers such as acetaminophen or ibuprofen.
- Hydration: Drinking plenty of fluids helps alleviate any potential side effects, such as dry mouth, caused by the anesthesia.
- Follow-up: A follow-up appointment is typically scheduled within one to two weeks to evaluate the effectiveness of the procedure and monitor recovery. If pain relief is achieved, additional injections may be scheduled as necessary.
Most patients can return to normal activities within a few days, but full pain relief may take up to a week to manifest. The effects of the nerve block can last from a few weeks to several months, depending on the medication used and the underlying condition.
Prognosis
The prognosis for patients receiving an ilioinguinal, iliohypogastric, or genitofemoral nerve block is generally positive, with most individuals experiencing significant pain relief. Studies suggest that 60-80% of patients report a reduction in pain of at least 50%, and many experience a lasting improvement in both pain levels and quality of life.
The duration of pain relief can vary depending on the underlying condition. For some, the effects may last for several months, while others may require repeat injections. In cases where the nerve block provides long-lasting relief, it can reduce the need for other pain management interventions, such as opioids or invasive surgeries.
In summary, ilioinguinal, iliohypogastric, and genitofemoral nerve blocks offer an effective, minimally invasive option for managing chronic pelvic pain, particularly when other treatments have been unsuccessful. By targeting specific nerves that transmit pain signals from the pelvic region, these blocks can provide significant relief and improve overall patient well-being.
