Post-herpetic neuralgia

Post-herpetic neuralgia is a complication of shingles, which is caused by the chickenpox (varicella zoster) virus. Most people who develop shingles have only one episode during their lifetime. However, you can have shingles more than once.

Causes

Post-herpetic neuralgia occurs when the nerves have been damaged after an outbreak of shingles. Nerve fibers are confused and send incorrect signals to your brain. The signals may be interpreted as pain that can last for a long period of time.

Symptoms

Symptoms of post-herpetic neuralgia are generally limited to the area of your skin where the shingles outbreak first occurred. They may include:

• Pain that lasts three months or longer
• Severe pain that may be constant, intermittent or triggered by even light touch
• Itching or numbness
• Headaches
• Fatigue
• Depression

Treatment

Treatment options for post-herpetic neuralgia include antidepressants, anticonvulsants, and painkillers. Topical treatments and skin patches may also be used.

Prevention

The best way to prevent post-herpetic neuralgia is to get vaccinated. The shingles vaccine can reduce your risk of shingles and the long-term pain it can cause.
