Dorsal Root Ganglion Therapy Treatment for Chronic Pain


June 16, 2023

Are you tired of living with chronic pain that seems to have no end in sight? If you’re seeking relief from painful conditions such as complex regional pain syndrome (CRPS) or neuropathic pain, you should consider Dorsal Root Ganglion (DRG) therapy to get permanent relief.

This post will shed light on DRG therapy, focusing on the use of regenerative medicine and interventional pain management techniques to help you understand how it can help you.

What is Dorsal Root Ganglion Therapy?

Dorsal Root Ganglion (DRG) therapy is an innovative interventional pain treatment that treats chronic pain by stimulating the dorsal root ganglion. The dorsal root ganglion is a cluster of nerves in the spinal cord that transmits pain signals to the brain.

The therapy involves the implantation of a neurotransmitter to deliver gentle pulses to the ganglion, in the process disrupting or modifying pain signals. This provides the patient with the much-needed relief from chronic pain and allows them to lead their life as close to normal as possible.

When to Use The Dorsal Root Ganglion Therapy

Traditionally, medical professionals consider and recommend DRG therapy when other pain management techniques have failed to provide the patient with adequate relief. However, as medical technology advances and research into DRG uncovers more techniques and benefits, it is becoming the go-to treatment for patients suffering from chronic pain.

If you suffer from such conditions as CRPS, chronic visceral pain, postherpetic neuralgia, and peripheral neuropathies in areas of the body such as limbs and lower back. Patients who have tried conventional spinal cord stimulation treatment and other chronic pain relief techniques without success may find the DRG therapy their most viable option.

Benefits of Dorsal Root Ganglion Therapy

Here is a set of benefits of using DRG therapy in treating chronic pain according to the National Library of Medicine.

  1. Targeted Approach: DRG therapy precisely targets the dorsal root ganglion, providing more focused pain relief compared to broader treatments.
  2. Enhanced Pain Control: By modulating the pain signals at their source, DRG therapy offers improved pain management and potentially enhances overall quality of life.
  3. Fewer Side Effects: Compared to systemic medications, DRG therapy has the advantage of delivering pain relief directly to the affected area, reducing the likelihood of systemic side effects.
  4. Customized Pain Relief: DRG therapy provides a highly customizable approach to chronic pain relief. The neurostimulator used in the therapy can be adjusted and programmed according to individual needs and preferences. This enables the fine-tuning of pain control to achieve optimal outcomes and maximize patient comfort.
  5. Long-Term Pain Management: DRG therapy has demonstrated promising long-term pain management results. Clinical studies have shown sustained pain relief for extended periods, allowing patients to experience a better quality life.

Risks of Dorsal Root Ganglion Therapy

  1. Infection and Bleeding: As with any surgical procedure, there is a risk of infection or bleeding at the site of the implantation.
  2. Device-related Complications: The neurostimulator may experience technical issues or require replacement, which can lead to additional surgeries.
  3. Nerve Injury: There is a small risk of nerve injury during the placement of the electrode near the dorsal root ganglion.

What to Expect from Dorsal Root Ganglion Therapy

Typically, DRG therapy is performed in stages starting with patient evaluation through to recovery and follow-up. Here is a four-step  summary of the process:

Step 1: Evaluation

The patient will first undergo a comprehensive evaluation to determine their suitability for DRG therapy. The evaluation often involves physical examinations, imaging, and discussions about the patient’s medical history.

Step 2: The Trial Period

A trial of the DRG therapy involves the implantation of a temporary electrode close to the dorsal root ganglion and connected to an external neurotransmitter. This step is used to evaluate the effectiveness of the therapy and to ascertain that the patient experiences a degree of pain relief.

Step 3: Permanent Implantation

If the trial period proves successful, a permanent neurostimulator will be implanted under the skin, typically in the abdomen or buttock area. This neurostimulator will deliver electrical pulses to the dorsal root ganglion.

Step 4: Recovery and Follow-up

After the permanent implantation, the patient will have a recovery period where they may experience some discomfort. Regular follow-up visits with the healthcare provider will be necessary to monitor the therapy’s effectiveness and address any concerns or complications that may arise.


Dorsal Root Ganglion Therapy offers hope for individuals living with chronic pain conditions. This targeted approach aims to provide effective pain relief and improve quality of life by utilizing regenerative medicine and interventional pain management techniques. While there are risks involved, the potential benefits make it a compelling option worth considering.
