Complications

Español: Complicaciones

The most common complication of shingles is a condition called post-herpetic neuralgia (PHN). People with PHN have severe pain in the areas where they had the shingles rash, even after the rash clears up.

The pain from PHN may be severe and debilitating, but it usually resolves in a few weeks or months in most patients. Some people can have pain from PHN for many years.

As people get older, they are more likely to develop PHN, and the pain is more likely to be severe. PHN occurs rarely among people under 40 years of age but can occur in up to a third of untreated people who are 60 years of age and older.

Shingles may lead to serious complications involving the eye. Very rarely, shingles can also lead to pneumonia, hearing problems, blindness, brain inflammation (encephalitis) or death.
