Then a distinctive rash can develop.
Why Does the Rash Usually Appear on One Side?
Shingles occurs when the dormant virus becomes active along a particular nerve.

This one-sided pattern is one of the characteristic features of shingles.
If you develop an unexplained painful or blistering rash—particularly on one side of your body—it’s worth contacting a healthcare professional promptly.

Most people recover from shingles, but complications can occur.
One of the most important is postherpetic neuralgia (PHN).
This condition causes nerve pain that continues after the shingles rash has healed. In some people, the pain can persist for months or even longer
