Acupuncture and TCM for postherpetic neuralgia (prolonged pain from shingles)

Post-herpetic neuralgia (PHN) is the most common complication and sequela of herpes zoster (HZ) that greatly affects the life and emotional experience of patients. There is no cure, but treatments can ease symptoms. For most people, postherpetic neuralgia improves over time. Acupuncture therapy has been confirmed as an effective and safe treatment for PHN.

What is post-herpetic neuralgia (PHN)- the prolonged pain from shingles?

Postherpetic neuralgia (PHN) is the most common complication of shingles. Once a person has chickenpox, the virus will always be in the body. Sometimes the virus becomes active again, causing shingles followed by PHN. PHN affects nerve fibers and skin, causing burning pain that lasts long after the rash and blisters of shingles disappear. The risk of postherpetic neuralgia increases with age, primarily affecting people older than 50. Around one in five people with shingles will get post-herpetic neuralgia. Many people with post-herpetic neuralgia make a full recovery within a year. But symptoms occasionally last for several years or may be permanent.

Symptoms of postherpetic neuralgia (PHN)

The signs and symptoms of postherpetic neuralgia are generally limited to the area of your skin where the shingles outbreak first occurred — most commonly in a band around your trunk, usually on one side of your body.

Signs and symptoms might include:

  • Pain that lasts three months or longer after the shingles rash has healed. The associated pain has been described as burning, sharp and jabbing, or deep and aching.

  • Sensitivity to light touch. People with the condition often can't bear even the touch of clothing on the affected skin (allodynia).

  • Itching and numbness. Less commonly, postherpetic neuralgia can produce an itchy feeling or numbness.

Risk factors

When you have shingles, you might be at greater risk of developing postherpetic neuralgia as a result of:

  • Age. You're older than 50.

  • Severity of shingles. You had a severe rash and severe pain.

  • Other illness. You have a chronic disease, such as diabetes.

  • Shingles location. You had shingles on your face or torso.

Complications

Depending on how long postherpetic neuralgia lasts and how painful it is, people with the condition can develop other symptoms that are common with chronic pain such as:

How long does postherpetic neuralgia (PHN) last?

Postherpetic neuralgia (PHN) can last for weeks, months, or in some people, years after the shingles rash goes away. In most people, shingles pain goes away in one to three months. However, in one in five people, pain lasts more than one year.

The pain from PHN can be so severe in some people that it disrupts their life. Researchers don’t know why some people have severe or long-lasting pain and others do not.

Traditional Chinese medicine’s understanding about Shingles

Acupuncture and herbs have been used to help the condition we recognize as shingles for over a thousand years. TCM philosophy views shingles as being related mainly to heat and dampness. As acupuncturists, we see shingles generally presenting in one of three ways:

Acupuncture and Herbs Stop Shingles Pain, Outperforms Drugs

Acupuncture and herbs prove effective for the treatment of shingles. Researchers from three independent studies [1-3] conclude that acupuncture and herbal medicine significantly relieve rashes and pain associated with the herpes zoster virus (shingles). Importantly, acupuncture and herbal medicine outperformed antiviral and anti-inflammatory medications, indicating that usual care protocols are suboptimal without inclusion of acupuncture and herbal medicine. -quoted from healthcmi.com

How Can Acupuncture Help postherpetic neuralgia (PHN)

Acupuncture therapy, including acupuncture, electroacupuncture, moxibustion, cupping, bloodletting etc., has been widely used in different pain conditions. Studies have shown acupuncture has a favorable effect on neuropathic pain.[4–6] Acupuncture therapy has already been confirmed to be effective in treating PHN, not only in relieving pain sensation, but also in improving the quality of life, anxiety, and depression.[7-10] Acupuncture and herbs can be used safely, alone or as an adjunct therapy, to relieve the herpes zoster rash and to prevent long-term nerve damage and pain due to neuralgia. TCM treatment also work holistically taking other symptoms of shingles, like headache and stomach upset into the regular course without the need for additional medications. In the long run, TCM can strengthen the immune system and prevent chronic illness.
