Postherpetic Neuralgia (PTN)

What is Postherpetic Neuralgia

Postherpetic neuralgia is a type of nerve pain that can develop after a shingles infection. Shingles, caused by the same virus that leads to chickenpox, triggers a painful skin rash. For many people, the rash heals and the pain fades. But in some cases, the discomfort lingers. When pain lasts for more than three months after the rash has gone, it’s known as postherpetic neuralgia.

This condition occurs because the shingles virus can damage the nerves. That damage may cause the nerves to send faulty pain signals to the brain, even after the skin appears to have recovered. As a result, the pain can persist and become chronic, interfering with daily life.

What Causes Postherpetic Neuralgia?

Postherpetic neuralgia begins with nerve damage caused by the shingles virus. During a shingles outbreak, the virus irritates the nerve fibers beneath the skin. If the nerves don’t heal properly after the rash goes away, they may continue to send pain signals. This ongoing nerve pain is what defines PHN.

People over 60 are more likely to develop this condition, especially if they had a severe case of shingles or a weakened immune system at the time of the outbreak. Age plays a significant role in risk, which is why early treatment for shingles is important.

Common Symptoms of Postherpetic Neuralgia

The most recognizable symptom of PHN is pain in the same area where the shingles rash appeared. This pain continues long after the visible rash disappears. It may feel:

  • Sharp or stabbing
  • Burning or throbbing
  • Like a shock or sudden jolt
  • Painful even with light touch, clothing, or changes in temperature

Some people also report tingling, numbness, or increased sensitivity in the affected area.

How Is Postherpetic Neuralgia Diagnosed and Treated?

A doctor can usually diagnose PHN by reviewing your medical history and asking about your symptoms. If you’ve had shingles and are still in pain months later, your provider will evaluate the area and discuss your treatment options.

Managing PHN can be challenging, but relief is possible. Treatments may include:

  • Topical creams: Certain creams or patches, such as those with capsaicin, can reduce surface pain.
  • Antidepressants: Some medications used for depression also help relieve nerve pain.
  • Anticonvulsants: Drugs like gabapentin or pregabalin can calm irritated nerves.
  • Nerve blocks: Injections of local anesthetic near the affected nerves may provide short-term relief.
  • Spinal cord stimulation: For severe or persistent cases, a small implanted device can help disrupt pain signals.

If you’re living with postherpetic neuralgia, it’s important to seek care early. A personalized treatment plan can reduce your symptoms and help you get back to doing the things you enjoy.
