Do you sometimes experience severe, unexplained pain in your lower abdomen or genital area? Perhaps this pain makes it difficult to sit or do normal tasks. Today we are talking about a special treatment method that doctors use in such cases. It is called a Pudendal Nerve Block.
Simply put, what is Pudendal Nerve Block?
This is actually an injection. To be precise, it involves injecting a pain-relieving medication into your pelvic region near the pudendal nerve. This can provide temporary or sometimes long-term pain relief.
Think about it, this pudendal nerve is a major nerve that carries sensation from the back of your pelvis to the muscles and skin in areas like your genitals, anus, vagina, and penis. If this nerve gets compressed or pinched in any way, it can cause chronic pelvic pain . In medicine, we call this pudendal neuralgia . This nerve block is mainly used to treat such conditions.
What are the uses of this vaccine?
This treatment method is used for three main purposes. Let's see what they are.
| Usage scenario | A simple explanation |
|---|---|
| For diagnosis (Diagnosis) | If you have pelvic pain but can't pinpoint the cause, your doctor may give you this injection. If your pain improves after the injection, it confirms that the cause is a problem with the pudendal nerve. If the pain doesn't improve, the cause may be something else. This can help you plan your treatment. |
| As a treatment | This injection is used to treat chronic pain caused by conditions such as pudendal neuralgia. This injection usually involves the addition of a local anesthetic and sometimes a corticosteroid to reduce swelling. |
| To numb an area (Regional Anesthesia) | This injection is used to numb only the area during some gynecological, obstetric, and rectal surgeries. For example, it is used to reduce pain in the vagina during childbirth, and during hemorrhoid surgery. This is a safer alternative to full anesthesia. |
How should you prepare for this?
This usually doesn't require much preparation.
However, sometimes your doctor may decide to put you to sleep (sedation) while you are receiving this injection. In this case, you will be advised to refrain from eating or drinking for about 6-8 hours . It is also essential to have someone to drive you home after the treatment.
However, your doctor will explain this to you beforehand. Follow those instructions exactly. Don't be afraid to ask any questions you have.
How to get vaccinated? What are the methods?
The doctor uses three main routes to administer this vaccine, depending on your body type and the purpose of the treatment.
Through the vagina (Transvaginal approach)
This method is most commonly used in obstetrics and gynecology.
- You will be made to lie down on a special bed, with your legs spread out and placed on top.
- A small injection (sedative) may be given into a vein in your arm to relax you.
- Then, the doctor inserts his hand inside the vagina and identifies where the nerve is located.
- Then, using a special instrument, the needle is carefully inserted into the nerve and the medicine is injected. Sometimes this is done with the help of scanning technologies such as ultrasound or fluoroscopy .
Through the area between the genitals and the anus (Transperineal approach)
This method is used for anal surgeries and pudendal pain in men.
- In this case, you will also be made to lie face up.
- The area of skin where the medicine will be injected is cleaned with an antiseptic solution.
- Then, the doctor inserts a finger into the rectum or vagina to find the exact location of the nerve.
- Then, the injection needle is inserted through the skin from the outside and the medicine is injected.
Perirectal approach
This method is also commonly used for anal surgeries and pudendal pain.
- In this, you are turned onto your side and made to lie down.
- As with other methods, the exact location of the nerve is located by inserting a finger or using a nerve stimulator .
- Then, the vaccine is given through the skin near the anus.
The important thing is that in all of these methods, a small injection is first given to numb the injection site. So you won't feel much pain. However, you may feel a little discomfort when the needle is inserted.
What are the benefits of this treatment?
- Temporary or permanent relief of pain: This can be a great relief to carry out your daily activities more easily.
- Reduces swelling: Reduces swelling in the nerve, helping it heal.
- Accurate diagnosis: This can help you determine whether or not the pudendal nerve is the real cause of your pain.
- Safety: This regional anesthesia method is much safer than general anesthesia.
Some people experience pain relief within minutes. If you are given a steroid injection, it may take a few days to feel its effects. However, we must remember that this does not relieve pain for everyone.
How successful is this? Are there any risks?
The success rate of this treatment varies from person to person, depending on the underlying medical condition causing the pain and other factors. On average, you can expect a success rate of more than 50%.
Speaking of risks, serious complications are very rare.
| Risk type | Things that could happen |
|---|---|
| Commonly seen side effects | There may be some pain or discomfort at the injection site for a couple of days. There may also be some bleeding or infection at the site. Sometimes there may be temporary numbness or weakness in the leg. |
| Serious but rare complications | Damage to the pudendal nerve, damage to nearby organs such as the bladder or rectum, and systemic local anesthetic toxicity can occur, but these are very rare. |
What time do you want to see the doctor again?
If you develop new symptoms after treatment, it means:
- If the injection site is severely swollen, red, or oozing pus (signs of infection).
- If there is burning pain, numbness, or persistent weakness .
- If you have an unusual fever.
If anything like this happens, call your doctor immediately.
