Herpes zoster (HZ) presents as a rash of 2-3 weeks duration in immunocompetent patients that is accompanied by moderate or severe pain. In some patients, pain does not resolve when the rash heals but continues for weeks and, sometimes, for months or years; this phenomenon is known as postherpetic neuralgia (PHN). PHN is the most troublesome side effect associated with HZ.
