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. However postherpetic neuralgia is also common in people whose shingles occurred on the face.

Signs and symptoms may include:

  • Pain that lasts 3 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.

When to see a doctor

See a doctor at the first sign of shingles. Often the pain starts before you notice a rash. Your risk of developing postherpetic neuralgia is lessened if you begin taking antiviral medications within 72 hours of developing the shingles rash.
