Shingles and Chickenpox (Varicella-Zoster Virus) - Complications

(Page 2)




Sometimes pain develops without a rash, a condition known as zoster sine herpete.

Herpes zoster (shingles) on the neck and cheek
This is a picture of herpes zoster (shingles) on the neck and cheek. The same virus that causes chickenpox is responsible for outbreaks of shingles. Outbreaks of shingles often follow the distribution of nerves in the skin. This distribution pattern is called a dermatome (see the "dermatomes" picture).

Postherpetic Neuralgia. Postherpetic neuralgia (PHN) is pain that persists for longer than a month after the onset of herpes zoster. Typical symptoms include:

  • Pain that is described as deep aching, burning, stabbing, or like an electric shock
  • Extreme sensitivity to touch or temperature changes
  • The pain is persistent, but may come and go.
