Herpes Zoster


Herpes zoster (HZ) is also called shingles. It is an infection caused by the same virus that causes chickenpox (varicella-zoster virus). After you get chickenpox, the virus stays in your body for several years without causing any symptoms. HZ occurs when the virus becomes active again. Once active, the virus will travel along a nerve to your skin and cause a rash.



You have the right to help plan your care. Learn about your health condition and how it may be treated. Discuss treatment options with your caregivers to decide what care you want to receive. You always have the right to refuse treatment.


If left untreated, HZ may cause eye problems, such as a drooping eyelid or blindness. It may lead to a brain infection or stroke. HZ can also cause nerve damage and lead to twitching, dizziness, or loss of taste and hearing. The blisters may leave scars or changes in skin color. HZ may cause pain even after the rash is gone. It may also lead to trouble moving parts of your body.
