What Is Shingles? Common Symptoms

This is a magnification of the herpes-zoster virus, which causes shingles.

Shingles is an illness caused by a reactivation of the varicella-zoster virus that causes chickenpox. It inflames sensory nerves and can result in severe pain. It causes localized pain, numbness, and itching, followed by the appearance of clustered blisters in a strip pattern on one side of the body. Sometimes the pain can persist for weeks, months, or years after the rash heals (known as post-herpetic neuralgia). The term "shingles" is derived from the Latin word cingulum, meaning girdle -- the idea being that the shingles rash often encircles the side of the body.

Shingles Virus

Shingles is caused by the same virus that causes chickenpox (varicella-zoster virus or VZV), a member of the herpes family of viruses.

Shingles is caused by the same virus that causes chickenpox (varicella-zoster virus or VZV), a member of the herpes family of viruses. After a person has chickenpox, the virus can live dormant in the nervous system in nerve fibers for life. Sometimes the virus remains dormant forever, but in other cases, the virus re-emerges or reactivates along a sensory nerve or dermatome.

Causes of Shingles Virus Reactivation

  • Disease
  • Stress
  • Aging

Each of these factors can weaken the immune system, resulting in varicella-zoster reactivation. However, usually a cause for the reactivation of the virus is never found. If the virus reactivates, it can only cause shingles, and does not cause widespread chickenpox viral infection again in the individual.

Shingles Rash Pictures

Herpes zoster results in a painful rash that may appear in one of several areas of the body.

The shingles rash appears as painful skin blisters that appear usually on only one side of the face or body along the distribution of nerves in the skin. The skin rash begins as fluid-filled blisters that then form scabs that may leave scars. The rash may occur around the chest, upper back, abdomen, face, the limbs, neck, or lower back. The rash usually appears in one or two adjacent dermatomes, which are parts of the skin that are supplied by a single spinal nerve.

Who Is at Risk of Shingles Virus?

Increasing age is a risk factor for shingles.

Shingles is most common in people over 60 years of age, although anyone who has ever had chickenpox (varicella) is at risk.


Risk Factors for Shingles Reactivation

  • Weakened immune systems
  • Immune deficiency (from AIDS or chemotherapy)
  • Emotional stress
  • Cancer

Up to 1,000,000 cases of shingles are estimated to occur each year in the U.S.

Shingles Symptoms: Before the Rash

People may experience pain before the rash caused by the varicella-zoster virus appears.

The pain of shingles may develop even when there is no rash. The patient may experience tingling, burning pain, or sensitive skin for several days to a week before the rash appears. It may be difficult to determine the cause of the severe pain in the absence of a skin rash.

Characteristics of Pre-Rash Shingles Pain

  • Itching
  • Burning
  • Tingling
  • Constant aching
  • Deep, shooting pain

Other Symptoms That May Occur Before Shingles Rash

  • Fever
  • Chills
  • Upset stomach
  • Headache

Shingles Symptoms: The Rash

A herpes zoster rash appears on a man's chest and torso.

The rash associated with herpes zoster begins as small blisters in a reddish background. New blisters form for the next few days, usually 3 to 5 days. Blisters emerge in a path of individual nerves in a specific "ray-like" distribution called a dermatomal pattern. Blisters tend to break out in a band-like pattern over an area of skin.

Shingles Symptoms: After the Rash

After zoster fluid-filled blisters pop, the lesions ooze, crust over, and then heal.

Just like the blisters of chickenpox, the blisters in shingles eventually burst, and the area starts to ooze. The blisters will then crust over and heal. Before the blisters crust over, the VZV virus can be spread to anyone who is not immune to chickenpox through vaccination or previous infection. Herpes zoster spreads when a person who lacks immunity has direct contact with the blisters of someone who has the virus. The scabs eventually fall off, and the rash disappears. Sometimes scarring may result.

How Long Does Shingles Last?

Younger people with strong immune systems are less likely to have long-term pain associated with herpes zoster than those who are older.

An outbreak of shingles can last for 3 to 4 weeks. Sometimes the pain is present but the blisters never appear. This can be a very confusing cause of pain. Some affected people develop post-herpetic neuralgia (PHN), in which the localized pain remains even after the rash is gone. For most people who suffer from post-herpetic neuralgia, the condition is not long-term, but resolves over time.

Shingles Complications: Postherpetic Neuralgia

Post-herpetic neuralgia is a potential complication of shingles that occurs when nerve pain persists for more than one month.

Postherpetic neuralgia (PHN) is the most common complication of shingles. This is defined as persistence of the nerve pain associated with shingles beyond one month, even after the rash is gone. It occurs from irritation of the sensory nerves by the virus. The pain of PHN can be severe and debilitating. Up to 15% of people with shingles develop PHN. Typically, this occurs in people over 50 years of age. Treatment of shingles with antiviral drugs can reduce the duration and occurrence of postherpetic neuralgia.

Is Shingles Contagious?

Chicken pox is an infectious disease that occurs when you come in contact with varicella-zoster virus, the same virus that causes shingles.

Shingles is contagious if you mean that the disease can transmit VZV to other people. Shingles can be spread from an affected person to babies, children, or adults who have not had chickenpox. Instead of developing shingles, these people develop chickenpox. Once they have had chickenpox, people cannot catch shingles (or contract the virus) from someone else. Once infected with VZV, however, people have the potential to develop shingles later in life if their immune system is run down or they experience some other stressor. Consequently, the disease of shingles itself is not contagious, only the VSV it produces is contagious. Thus, some experts say both yes and no to the contagious question.

Shingles is contagious to people who have not previously had chickenpox when there are new blisters forming and old blisters healing. Like with chickenpox, the time prior to healing or crusting of the blisters is the contagious stage of shingles. After all of the blisters are crusted over, the contagious period is over and the virus can no longer be spread.

Other Shingles Complications

Shingles that spreads to the eye may lead to vision loss.

Usually, shingles heals well and remaining problems are minimal. However, complications may arise from time to time.


Cellulitis

On occasion, shingles blisters can become infected with bacteria, resulting in cellulitis. Cellulitis is a bacterial infection of the skin. When cellulitis occurs, the skin area turns reddened, warm, firm, and tender.

Vision Loss

A more worrisome complication occurs when shingles affects the face (forehead and nose), which may spread to the eye and lead to loss of vision. Shingles that affects the eyes is called herpes zoster ophthalmicus.

Other Complications

Shingles may also be associated with complications that affect the ears, which can affect hearing or balance. Shingles may weaken muscles on the side of the face. Rarely, shingles may spread to the brain or spinal cord, which can lead to a stroke or meningitis. Shingles may also trigger an immune reaction that affects blood vessels (vasculopathy). People who have shingles have a slightly increased risk of stroke within the first few weeks of the blisters appearing. This increased risk may last for several months.

How Is Shingles Diagnosed?

A zoster rash appears on the neck of a patient.

The clinical appearance of shingles is usually sufficient for a doctor to establish the diagnosis. Diagnostic tests are not usually required. However, particularly in people with impaired immune function, shingles may sometimes not have the characteristic clinical pattern. In this situation, samples from the affected skin may be examined in a laboratory, either by culturing the tissue for growth of the virus or by identifying the genetic material of the varicella virus.

Shingles Treatment

Antiviral treatment for shingles is most effective when taken early after a flare-up.

You can take steps to reduce the duration of a shingles outbreak, but in the end, the virus must often simply run its course. There is no cure for shingles. Antiviral medication is effective only if given early, so it is important to visit your doctor soon after an outbreak starts or is suspected Those with facial, nose, or eye symptoms should seek medical care immediately. Early medical attention may also prevent or reduce any scarring.

Shingles Treatment: Drugs

Take medication as directed by your doctor to control shingles outbreaks, pain, and inflammation.

There are many drugs used to fight shingles and its symptoms. This is an explanation of those drugs and their functions.


Antiviral Drugs

Drugs that fight viruses (antiviral drugs), such as acyclovir (Zovirax), valacyclovir (Valtrex), or famciclovir (Famvir), can reduce the severity and duration of the shingles rash if started early (within 72 hours of the appearance of the rash).


Pain Medications

In addition to antiviral medications, pain medications may be given. Both nonsteroidal anti-inflammatory medications and narcotic pain-control medications may be used for pain management in shingles. Postherpetic neuralgia (PHN) may require additional medications to control pain.


Topical Corticosteroids

Topical corticosteroids are sometimes used to decrease inflammation and pain, but these should be used only under the supervision of a health care professional since in some patients, corticosteroids may make the condition worse.

Shingles Treatment: Home Remedies

Baths and calamine lotion are a few home treatment options for shingles.

Bathing is generally allowed, and the affected area can be washed with soap and water. Cool compresses and anti-itching lotions such as calamine lotion may also provide relief from symptoms. An aluminum acetate solution (Burow's or Domeboro solution, available at pharmacies) can be used to help dry up the blisters and oozing. Application of petroleum jelly can also aid in healing. Over-the-counter (OTC) antihistamines, such as diphenhydramine (Benadryl) and pain medicines can also help provide relief.

Wearing loose clothing can help avoid extra pain from clothing rubbing against the rash. Avoid close skin-to-skin contact with others who have not had chickenpox, are ill, or who have a weakened immune system to avoid spread of the virus. People who do not have immunity to the virus may catch varicella by having direct contact with the lesions. In this way zoster is similar to cold sores, which are caused by a virus in the same family as varicella.

Shingles Vaccine

A woman receives the shingles vaccine.

In May 2006, the U.S. Food and Drug Administration (FDA) approved the first vaccine for adult shingles. The vaccine is known as Zostavax and is approved for use in adults ages 60 and over who have had chickenpox. The U.S. Centers for Disease Control and Prevention (CDC) recommends the vaccine for people 60 years of age and over who have had chickenpox. It is a onetime injection that contains a booster dose of the chickenpox vaccine that is given to children. An additional shingles vaccine called Shingrix was approved in 2017. It is administered according to a two-dose schedule and is the preferred shingles vaccine for healthy adults age 50 years and older.

Tests showed that the vaccine significantly reduced the incidence of shingles in older adults. The single-dose vaccine was shown to be more than 60% effective in reducing shingles symptoms, and it also reduced the incidence of post-herpetic neuralgia (PHN) by at least two-thirds. Even if you have had shingles, you can still have the vaccine to help prevent future outbreaks. Shingrix is even more effective in preventing shingles and post-herpetic neuralgia. Shingles is largely a vaccine-preventable illness.

Who Should Avoid the Shingles Vaccine?

Pregnant women should not receive the shingles vaccine.

Some people should not receive the shingles vaccine, including pregnant women and those with significantly suppressed immune systems.

Pregnant Women

The shingles vaccine should not be given to pregnant women. It is recommended that a woman wait three months before trying to become pregnant after she has received the shingles vaccine.

People With Weakened Immune Systems

People with weakened immune systems due to immune-suppressing medications, HIV disease, cancer treatment, or organ transplants should not receive the shingles vaccine because it contains live, weakened virus particles.

People Under Age 60

There is not enough information available to determine whether Zostavax may be generally beneficial in people younger than 60 years of age.

Shingles Vaccine Side Effects

Some people experience side effects after receiving the shingles vaccine.

The shingles vaccine has not been shown to cause any serious side effects or health consequences. Minor side effects of the vaccine include redness, swelling, soreness, or itching at the site of injection, and headache. It is safe for those who have received the shingles vaccine to be around babies or those with weakened immune systems. It has not been shown that a person can develop chickenpox from getting the shingles vaccine, although some people who receive the vaccine may develop a mild chickenpox-like rash near the injection site. This rash should be kept covered and will disappear on its own.

Shingles Risks and Pregnancy

Shingles in pregnancy is rare, but it can occur and it is treatable.

Pregnant women are susceptible to shingles. Fortunately, shingles in pregnancy is very rare. The antiviral medications described previously are considered safe to use in pregnant women, as are most pain-relieving drugs. Women should not take nonsteroidal anti-inflammatory medications such as ibuprofen (Advil) or naproxen (Aleve) in the later stages of pregnancy, but acetaminophen (Tylenol) is considered safe. Having chickenpox during pregnancy has the potential to cause birth defects, depending upon when in the pregnancy the infection occurs. The risk of birth defects is believed to be lower with shingles than with primary chickenpox infection.
