Shingles is a viral infection that causes a painful rash. Although shingles can occur anywhere on your body, it most often appears as a single stripe of blisters that wraps around either the left or the right side of your torso.
Shingles is caused by the varicella-zoster virus — the same virus that causes chickenpox. After you've had chickenpox, the virus lies inactive in nerve tissue near your spinal cord and brain. Years later, the virus may reactivate as shingles.
While it isn't a life-threatening condition, shingles can be very painful. Vaccines can help reduce the risk of shingles, while early treatment can help shorten a shingles infection and lessen the chance of complications.

The signs and symptoms of shingles usually affect only a small section of one side of your body. These signs and symptoms may include:
Some people also experience:
Pain is usually the first symptom of shingles. For some, it can be intense. Depending on the location of the pain, it can sometimes be mistaken for a symptom of problems affecting the heart, lungs or kidneys. Some people experience shingles pain without ever developing the rash.
Most commonly, the shingles rash develops as a stripe of blisters that wraps around either the left or right side of your torso. Sometimes the shingles rash occurs around one eye or on one side of the neck or face.
Contact your doctor promptly if you suspect shingles, but especially in the following situations:

Shingles is caused by the varicella-zoster virus — the same virus that causes chickenpox. Anyone who's had chickenpox may develop shingles. After you recover from chickenpox, the virus can enter your nervous system and lie dormant for years. Eventually, it may reactivate and travel along nerve pathways to your skin — producing shingles.
The reason for the encore is unclear. But it may be due to lowered immunity to infections as you grow older. Shingles is more common in older adults and in people who have weak immune systems.
Varicella-zoster is part of a group of viruses called herpes viruses, which includes the viruses that cause cold sores and genital herpes. Because of this, shingles is also known as herpes zoster. But the virus that causes chickenpox and shingles is not the same virus responsible for cold sores or genital herpes, a sexually transmitted infection.
A person with shingles can pass the varicella-zoster virus to anyone who isn't immune to chickenpox. This usually occurs through direct contact with the open sores of the shingles rash. Once infected, the person will develop chickenpox, however, not shingles.
Chickenpox can be dangerous for some groups of people. Until your shingles blisters scab over, you are contagious and should avoid physical contact with:

Shingles is usually diagnosed based on the history of pain on one side of your body, along with the telltale rash and blisters. Your doctor may also take a tissue scraping or culture of the blisters for examination in the laboratory.

Two vaccines may help prevent shingles — the chickenpox (varicella) vaccine and the shingles (varicella-zoster) vaccine.
The varicella vaccine (Varivax) has become a routine childhood immunization to prevent chickenpox. The vaccine is also recommended for adults who've never had chickenpox. Though the vaccine doesn't guarantee you won't get chickenpox or shingles, it can reduce your chances of complications and reduce the severity of the disease.
The Food and Drug Administration has approved the use of the varicella-zoster vaccine (Zostavax) for adults age 50 and older. Like the chickenpox vaccine, the shingles vaccine doesn't guarantee you won't get shingles. But this vaccine will likely reduce the course and severity of the disease and reduce your risk of postherpetic neuralgia.
The shingles vaccine is used only as a prevention strategy, however. It's not intended to treat people who currently have the disease. The vaccine contains live virus and should not be given to people who have weakened immune systems.

Taking a cool bath or using cool, wet compresses on your blisters may help relieve the itching and pain. And, if possible, try to reduce the amount of stress in your life.

Anyone who has ever had chickenpox can develop shingles. Most adults in the United States had chickenpox when they were children, before the advent of the routine childhood vaccination that now protects against chickenpox.
