DRG Therapy Blocks Chronic Pain

June 23, 2020

What is it?

The Dorsal Root Ganglion Stimulation is a non-opioid therapy specifically designed to help manage chronic nerve pain. Similar to the traditional Spinal Cord Stimulation, DRG therapy targets specifics regions of the spinal cord that are transmitting painful signals from your lower limbs to your brain. When these signals pass through the Dorsal Root Ganglion, the stimulation sends mild electrical pulses to the nerves responsible for the painful sensations. 

What does it feel like?

By the time the pain signals reach your brain and will manifest as physical pain, they are weakened. Pain interrupting signals are sent out from a battery-operated device called a spinal cord stimulator which a pain doctor implants under the skin. A small wire, equipped with electrodes, delivers mild pulses of electricity to the nerves in the spinal cord. These pulses interfere with pain signals leaving the spine, causing them to be significantly weakened by the time they reach the brain. The patient turns the spinal cord stimulator on and off and adjusts the settings with a handheld remote control unit.

DRG Therapy and Knee Pain

Do you suffer from chronic pain in your knees? The knee area contains multiple nerves. During knee surgery, even with the utmost care, a nerve can be injured. The nerve pain that may develop from this injury if often life-lasting. If your pain has lasted longer than six months, hasn’t been satisfied with other treatment options, and/or impacts your everyday life- you may consider DRG therapy. 

DRG stimulation has been successfully used as a nerve block for chronic leg pain, such as complex regional pain syndrome (CRPS) and causalgia (CRPS type II).

Dr. Moore was one of the first physicians certified for DRG therapy in the North Houston area.  At Pain Management Center of Houston, we would love to further discuss your condition and your options towards a pain-free life!

Learn more about some of the common causes of abdominal pain that we treat at our office in The Woodlands.
The pelvic region of the body is located between the abdomen and the thighs (below the belly button and above the legs.) The pelvis protects internal organs including the bladder, intestines, and reproductive organs and supports the hip joints.

Chronic abdominal pain is noticeable but not crippling pain that lasts for more than a few days. It may also appear on and off over the course of several months. This type of persistent, nagging abdominal pain may be caused by a condition that needs to be treated, but is not an emergency and won’t go away on its own.

Reproductive Conditions
Chronic pelvic pain in women may be caused by:

  • Endometriosis - when uterine tissue grows in other parts of the body, including the pelvis, causing pain and scarring
  • Fibroid tumors - non-cancerous growths in or on the uterus

In men, it may be caused by prostatitis (inflammation of the prostate).

In men or women, chronic pelvic pain may be due to irritable bowel syndrome (IBS), interstitial cystitis (a common bladder problem) or another condition of the digestive tract.

Pudendal Neuralgia
The pudendal nerve is the main nerve in the pelvis that supplies sensation to the lower buttocks, anal region, and genital region of both men and women. Pudendal neuralgia is a condition that occurs when this nerve is damaged or irritated. Symptoms of pudendal neuralgia include pelvic pain that feels like a burning, shooting, or prickling sensation. Pain may develop suddenly or gradually and may be constant but worse while sitting down. Other symptoms may include numbness in the pelvic region, pain during sex, and feeling a swelling sensation in your buttocks and genital regions.
Tailbone Pain
The tailbone, also known as the coccyx, is the small, triangular bone at the bottom of the spine. Tailbone pain is usually caused by trauma to the area resulting from

  • a fall
  • a blow to the area
  • repetitive friction in the area – from bicycling, for example
  • prolonged sitting on a hard surface
  • joint degeneration
  • injury to a woman’s tailbone during childbirth

Symptoms of tailbone injury include severe, localized pain and tenderness and possibly bruising.

What is Radiofrequency Ablation?
After identifying which spinal nerves are causing a patient’s back pain, the doctor performs radiofrequency ablation to deactivate the part of those nerves that are signaling pain. Guided with x-ray imagery, the doctor guides a tiny probe into the spinal area until it is positioned next to the targeted nerve. Electrical pulses are passed through the probe, heating it up and destroying the part of the nerve that was sending pain signals to the brain. The targeted nerves still function, they’re just unable to transmit pain sensations.

There is a numbing agent given to the local area being treated. The patient remains awake during the procedure that usually takes less than an hour. Patients are able to go home the same day.

What is COOLIEF* Radiofrequency Ablation?
Like other radiofrequency ablation procedures, COOLIEF* disrupts pain signals. Unlike other radiofrequency ablation procedures, COOLIEF* uses water-cooled technology. Water is circulated through the probe at the same time the nerves are being heated. This creates a larger treatment area that leads to better, long-term pain relief and ensures that pain-transmitting nerves being targeted are not overheated, which protects surrounding muscle tissues from side effects like inflammation. COOLIEF* is simply a better version of a proven pain-relieving procedure.
