What is a Nerve Block? Is it a solution to your pain?

Do you sometimes have unbearable back pain, knee pain, or a constant headache? Some pains just don't go away with medication, right? Today we're going to talk about a special treatment method that doctors use in such cases. This is called a nerve block.

Simply put, what is a nerve block?

Think of the nerves in our bodies as cables. These cables carry messages from our brain to other parts of our bodies, and from parts of our bodies to our brain. Everything you feel, like pain and touch, as well as moving your limbs and breathing, is controlled by these messages.

A nerve block is a drug injected near a specific nerve or group of nerves that is causing pain. This temporarily "blocks" the pain message from going to the brain, like closing a road for a while. This injection is combined with a local anesthetic and sometimes a medicine to reduce swelling. This also gives the nerves that have been damaged by the swelling a chance to heal.

Although the effects of this are felt quickly, it is often a temporary solution. Some people get relief with one injection, while others need several. Sometimes it may not have any effect at all. In that case, other treatments must be sought.

What are the reasons for a nerve block?

A nerve block is done for three main purposes. To make it easier to understand, let's look at it this way.

Purpose of treatment Simply put...
As a treatment (Therapeutic) Provide temporary relief from acute or chronic pain. This reduces swelling in the nerve, helping it heal and reducing pain.
For a diagnosis (Diagnostic) Imagine you have pain somewhere, but the doctor can't pinpoint where the pain is coming from. Then he or she will perform a nerve block on the suspected nerve. If the pain goes away after the injection, that means the problem is with that nerve. If the pain doesn't go away, the cause is somewhere else. This will help the doctor plan your next course of treatment.
As an anesthetic This method is used to control pain before and after surgery. It is given along with general anesthesia for major surgeries. For minor surgeries on the hand (for example, carpal tunnel surgery), a nerve block may be used instead of general anesthesia.

What types of nerve blocks are there?

Since there are hundreds of major nerves in our body, there are many types of nerve blocks. Let's look at a few of the most commonly used types.

  • Celiac plexus nerve block: This is done to a group of nerves in the upper abdomen, behind the pancreas. It helps relieve pain caused by pancreatic cancer or chronic pancreatitis.
  • Epidural nerve block: You've probably heard of this one before. It's famous for reducing pain during childbirth. But it's also used for surgery. It works by numbing pain in one area of ​​the body, like the legs or abdomen.
  • Genicular nerve block: This is done to the nerves around the knee joint. It provides relief for chronic knee pain and severe knee pain after surgery.
  • Intercostal nerve block: These nerves are located under your ribs. This can help provide temporary relief from pain caused by rib fractures and help diagnose and treat nerve pain (neuralgia).
  • Lumbar sympathetic nerve block: These nerves are located on either side of the spinal cord, in the lower back. This provides relief from back and leg pain, for example, sciatica.
  • Occipital nerve block: This nerve is located at the back of your head. This block, which starts at the vertebrae in your neck, treats a type of headache called occipital neuralgia. It can also help control severe migraines.
  • Trigeminal nerve block: This nerve is located on each side of your face. It is used to treat various types of facial pain, especially a condition called trigeminal neuralgia.

How does this work inside the body?

To understand how this works, let's first look at how our bodies feel pain.

1. Our nerves have special receptors called nociceptors. These are like sentinels on alert. They are activated immediately if the body is damaged or injured.

2. At the same time, these sentinels send high-priority signals to the brain, saying, "There's a problem here!" These aren't pain itself, they're like a message sent in coded language.

3. The brain receives these signals, understands that code, and translates it into the sensation of "pain."

What the anesthetic in a nerve block does is stop the nerve cells from sending coded messages. That is, it blocks the message halfway through. Then, because the message about pain doesn't get to the brain, you don't feel the pain.

Sometimes, the swelling that occurs in response to an injury can last for a long time. That can also cause ongoing pain. The medications in a nerve block reduce that swelling and give the nerve time to heal. That can also reduce pain.

How do you prepare for a nerve block? What happens during and after it's done?

Let's look at this process step by step.

Before treatment...

Usually, a nerve block does not require much preparation. However, sometimes the doctor may decide to give you a medicine to make you feel light-headed (sedation). If this happens, you will be asked to fast for about 6-8 hours. Also, it is essential that someone takes you home after the treatment. However, your doctor will explain all this to you beforehand. Follow those instructions exactly. Don't be afraid to ask if you have any questions.

During treatment...

This is usually done on an outpatient basis. This means you don't have to stay in the hospital and can go home shortly after the treatment.

  • First, you will be asked to lie in a specific position on an examination table to make it easier for the doctor to give you the injection.
  • You may be given medicine through an IV line in your arm to make you feel more relaxed.
  • The injection site is cleaned with a disinfectant solution.
  • Then, a small injection of local anesthetic is given to numb the area where the nerve block will be performed. You may feel a slight stinging sensation as the needle goes in.
  • Next, the doctor uses technology such as ultrasound or X-ray to find the exact spot to inject the vaccine.
  • Then, the medicine is injected as close as possible to the nerve in question.
  • After the treatment, you will be told to rest for a while until the medicine takes effect.

After treatment...

You will need to rest for about 15-30 minutes after the injection. During this time, the medical staff will watch you for any unusual side effects. If everything is fine, you will be allowed to go home.

What are the benefits and risks of this?

Benefits

  • Temporary or sometimes permanent pain relief, allowing you to carry out your daily activities more easily.
  • The swelling of the affected nerve is reduced, helping it to heal.
  • Helping to identify the specific cause of the pain (a diagnosis).

The important thing is that not everyone gets pain relief from nerve blocks. Sometimes, other treatments may need to be considered.

Risks and Complications

The risk of complications from a nerve block is very low , but it's important to be aware.

  • Infection at the injection site.
  • Bleeding from the injection site.
  • Accidental injection of medication into a blood vessel.
  • The drug spreads unexpectedly to other nerves or into the spinal cord.

Each type of nerve block may have different risks, so be sure to discuss the benefits and risks of the nerve block you are considering with your doctor.

How long will this pain relief last?

This varies greatly from person to person. Some people may go a few days without pain. Others may have weeks, months, or even years of relief. Some people may get relief with just one injection, while others may need several treatments. Some may not get any relief at all.

What time do you need to talk to the doctor?

If you develop any new symptoms after treatment, such as infection (redness, swelling, pus) at the injection site, inflammation, severe pain, numbness, or weakness, notify your doctor immediately without delay.

Nerve blocks are a great way to treat a variety of pain conditions, but results vary from person to person. If you have any concerns or questions about this injection, talk to your doctor. He or she will be able to answer all your questions.

Take-Home Message
