Postherpetic neuralgia (PHN) is a type of long-lasting nerve pain that follows a shingles outbreak, which stems from the reactivation of the dormant varicella-zoster virus. This condition arises when shingles-related nerve damage causes the brain to misinterpret pain signals, often leading to burning, throbbing, or electric shock-like sensations. PHN is particularly common in older adults and individuals with compromised immune systems, especially those who experience intense rash and acute pain during their shingles episode.
