The onset of the disease is sudden. Before the eruption, there may be mild systemic symptoms such as low fever, fatigue, general discomfort, and needling or burning pain on the affected skin. When the pain is severe, it may be misdiagnosed as acute abdomen and other diseases. The most common sites were chest (intercostal nerve distribution area) and forehead (trigeminal nerve distribution area), followed by neck, abdomen and limbs

The rash is characterized by groups of bright blisters with the size of mung bean to rice grain. The base is red and distributed along one side of the peripheral nerve. The skin between each group of blisters is normal. The blisters burst about 1 or 2 weeks, scab or dry absorption. Pigmentation is left after decrustation. A few serious cases can be generalized systemic, known as generalized herpes zoster.

Herpes zoster is often accompanied by neuralgia, which can occur before eruption, when eruption and after skin lesion recovery, but most of them disappear after skin lesion completely subsides or within 1 month. Neuralgia in a few patients can last more than 1 month, which is called postherpetic neuralgia.
