The Potential of Nerve Block Injections in Chronic Migraine Treatment

The Potential of Nerve Block Injections in Chronic Migraine Treatment


As someone who has personally experienced the debilitating effects of chronic migraine attacks, I understand the constant search for effective treatments. When traditional approaches failed to provide relief, I began exploring alternative options, leading me to discover the potential benefits of nerve block injections.

What are Nerve Block Injections?

Nerve block injections are a minimally invasive procedure involving the use of local anesthesia to numb specific nerves associated with migraine pain. These injections are targeted at trigger points in the body, such as the occipital nerves at the back of the head, to alleviate the pain caused by migraine attacks.

For example, in an occipital nerve block, the healthcare provider injects a numbing medication near the occipital nerves located at the back of the head. This effectively blocks the pain signals transmitted through these nerves, providing relief in the upper neck and back of the head.

Effectiveness of Nerve Block Injections

From my personal experience with nerve block injections, I have observed a significant reduction in the frequency and intensity of my migraine attacks. This improvement has greatly enhanced my overall quality of life. Research studies and clinical trials have also shown promising results in preventing migraine attacks and reducing the need for pain medication.

For instance, a study published in the journal Headache found that patients who received occipital nerve blocks experienced a significant decrease in the number of headache days per month compared to those who did not receive the injections. Additionally, a study published in the British Journal of Anaesthesia reported a decrease in pain intensity and analgesic (pain medication) consumption in patients who underwent nerve block injections.

How do Nerve Block Injections Work?

Nerve block injections work by blocking the pain signals from reaching the brain. They also help reduce inflammation around the nerves and relax the muscles, relieving tension that often accompanies migraine attacks. By targeting these physiological aspects, nerve block injections provide effective relief.

Types of Nerve Block Injections for Migraine Attacks

There are several types of nerve block injections used to treat migraine attacks:

1. Occipital Nerve Blocks

Occipital nerve blocks involve targeting the occipital nerves located at the back of the head. By injecting numbing medication near these nerves, pain relief is experienced in the back of the head and upper neck.

For example, suppose an individual frequently experiences migraine attacks that originate from the back of their head and radiate to the upper neck. In that case, an occipital nerve block can specifically target and alleviate the pain in these areas.

2. Supraorbital Nerve Blocks

Supraorbital nerve blocks involve targeting the supraorbital nerve, which is located above the eye. Injecting numbing medication at this site can provide relief for migraine attacks in the forehead and eye area.

3. Greater Occipital Nerve Blocks

Greater occipital nerve blocks target the greater occipital nerve at the base of the skull. By numbing this nerve, pain can be alleviated in the back of the head, temples, and eye area.

Benefits of Nerve Block Injections

Nerve block injections offer several benefits for individuals suffering from chronic migraine attacks:

  • Immediate pain relief, which can provide a much-needed respite from migraine attacks.
  • Minimal side effects compared to other treatment options.
  • Non-invasive procedure that can be administered in a healthcare professional’s office.
  • Long-lasting results, allowing individuals to experience relief from migraine attacks for an extended period.

Considerations before Undergoing Nerve Block Injections

Prior to opting for nerve block injections, it is crucial to consider the following:

  • Consult with a qualified healthcare professional who specializes in treating migraine attacks.
  • Understand the potential risks and benefits associated with nerve block injections.
  • Discuss any allergies or adverse reactions you may have experienced in the past.

Personal Tips for Managing Nerve Block Injections

Based on my personal experience, here are some tips for managing nerve block injections:

  • Practice relaxation techniques before and during the procedure to minimize any discomfort or anxiety.
  • Maintain open communication with your healthcare provider and address any concerns or questions you may have.
  • Document the frequency and intensity of your migraine attacks before and after the injections to track the efficacy of the treatment.

Frequently Asked Questions

1. Are nerve block injections a permanent solution for chronic migraine attacks?

Nerve block injections provide temporary relief and may need to be repeated at regular intervals. Some individuals may experience longer-lasting effects, but it varies from person to person.

2. Are there any side effects of nerve block injections?

The most common side effect is temporary injection site discomfort. In rare cases, nerve damage or infection may occur. It is essential to discuss the potential risks with your healthcare provider before undergoing the procedure.

3. Can nerve block injections be combined with other migraine treatments?

Yes, nerve block injections can be used alongside other migraine treatments, such as medication or lifestyle modifications. Your healthcare provider can determine the best combination for your specific needs.

4. How long does it take for nerve block injections to start working?

The onset of relief varies among individuals. Some may experience immediate relief, while for others, it may take a few days for the full effects to be felt.

5. Do nerve block injections hurt?

During the procedure, you may feel a brief discomfort similar to a pinprick or bee sting. However, the healthcare provider will use local anesthesia to minimize any pain or discomfort.

6. Are nerve block injections covered by insurance?

Insurance coverage for nerve block injections may vary. It is advisable to check with your insurance provider regarding coverage details for this specific treatment.

7. Are there any lifestyle changes I should make alongside nerve block injections?

While nerve block injections can provide relief, certain lifestyle changes such as managing stress, getting regular sleep, and avoiding triggers may also contribute to managing migraine attacks effectively.

8. How long does the effect of nerve block injections last?

The duration of pain relief varies among individuals. Some may experience relief for several weeks, while others may require more frequent injections. Your healthcare provider can guide you on the optimal schedule for repeat injections.

9. Can anyone undergo nerve block injections for migraine attacks?

Nerve block injections are generally safe and suitable for many individuals. However, specific medical conditions or allergies may restrict their use. It is essential to consult with a healthcare professional to determine if nerve block injections are a viable treatment option for you.

10. Can nerve block injections cure migraine attacks?

Nerve block injections do not provide a permanent cure for migraine attacks. However, they can significantly reduce the frequency and intensity of migraine attacks, resulting in improved quality of life.


The potential of nerve block injections in the treatment of chronic migraine attacks cannot be understated. From my personal success story to the positive research findings, this alternative treatment option offers hope for individuals seeking relief from the burdensome effects of migraine attacks. I encourage others to explore the potential benefits of nerve block injections and discuss this option with their healthcare providers.
