Shingles: Signs, Symptoms and Treatment with Dr. Mark Shalauta | San Diego Health

An antiviral medication can:

Reduce the amount of time that you have a shingles rash
Lower your risk of developing long-lasting nerve pain and other health problems

One of three antiviral medications is usually prescribedacyclovir, famciclovir, or valacyclovir.

To treat your symptoms, dermatologists typically recommend the following:

If you have severe pain, your dermatologist may prescribe a medication that reduces inflammation, such as a corticosteroid.

Diagnostic Tests For Shingles

There can be a painful rash on your body if you have shingles . There can be shingles anywhere on your body. The varicella-zoster virus is the main cause of shingles. This same virus causes chickenpox. If you had chickenpox, the virus often remains inactive in the nerve tissue near your spinal cord and brain after the attack of chickenpox is over. The virus may reactivate after many years as shingles. If there is a rash on your body, the doctor can make an accurate clinical diagnosis by examining the signs and symptoms of shingles. There may be difficulty in diagnosing shingles if there is no rash on the body. It may be confused with some other conditions. The doctor suggests some diagnostic tests in such cases to confirm the presence of shingles. A diagnostic centre in Uttarpara has expert technicians to carry out these tests.

What Does The Test Result Mean

Care must be taken when interpreting the results of VZV testing. The health care practitioner evaluates the results in conjunction with clinical findings. It can sometimes be difficult to distinguish between a latent and active VZV infection. This is possible for several reasons, including:

A healthy person who has been infected with VZV will continue to harbor the virus after the symptoms disappear. The VZV can reactivate intermittently, shedding small amounts of virus into body fluids but not causing symptoms.
An infant or immunocompromised person may not have a strong antibody response to the VZV infection their IgM and IgG levels may be lower than expected even though the person has an active case of VZV.
The virus may not be present in sufficient number in the particular fluid or tissue tested to be detected.

Antibody detectionIf both VZV IgG and IgM are present in a symptomatic person, then it is likely that the person has either recently been exposed to VZV for the first time and has chickenpox or that the previous VZV infection has been reactivated and the person has shingles.

Viral detectionIf someone is symptomatic and the culture is positive for varicella zoster virus, then the person likely has an active VZV infection. If the culture is negative, then the persons symptoms may be due to another cause or the VZV virus is not detectable in the sample tested.

Higher Intensity Of Pain With Internal Shingles

While both regular shingles and internal shingles can cause preherpetic neuralgia, this condition has been found to be more severe in the latter case.

One study found that at the onset of symptoms, after one month, and after three months, internal shingles patients had consistently more severe and persistent pain. Overall, however, preherpetic neuralgia occurs much more frequently in regular herpes zoster patients.

How Is Shingles Treated

Specific treatment for shingles will be determined by your healthcare provider based on:

Your age, overall health, and medical history
How long the shingles have been present
Extent of the condition
Your tolerance for specific medicines, procedures, or therapies
Expectations for the course of the condition
Your opinion or preference

There is no cure for shingles. It simply has to run its course. Treatment focuses on pain relief. Painkillers may help relieve some of the pain. Antiviral drugs may help lessen some of the symptoms and reduce nerve damage. Other treatments may include:

Creams or lotions to help relieve itching
Cool compresses applied to affected skin areas
Antiviral medicines
Anticonvulsants

Quick Answers For Clinicians

Traditionally, clinical features were considered diagnostic for varicella-zoster virus . However, the decrease in disease occurrence and severity due to vaccination has likely caused a decrease in the positive predictive value of clinical diagnosis alone. This can likely be attributed to multiple factors. The first is that fewer clinicians have direct experience with natural infection. The second is that infection can present atypically in vaccinated individuals . As a result, the need for laboratory testing for definitive diagnosis has increased. The CDC criteria for VZV diagnosis includes positive identification of VZV by polymerase chain reaction testing, direct fluorescent antibody staining, culture, or serology. If VZV infection is strongly suspected due to canonical presentation, treatment should not be delayed pending laboratory results.

There are many uncommon presentations and complications associated with varicella-zoster virus . Abnormal presentations include VZV pneumonitis, varicella encephalitis, and VZV vasculopathy. These often require appropriate clinical evaluation to determine the best laboratory testing strategy and sample types. In some cases, the etiologic agent responsible for skin lesions may be unclear, and laboratory testing can determine the cause of symptoms.

The CDC recommends vaccination against varicella and herpes zoster. More information about these recommendations can be found at the following links:

Other things you can do include:

Eat a healthy diet.
Aim for seven to nine hours of sleep each night.
Dont smoke or use tobacco products.

These are all tips for an overall healthy lifestyle, not just for reducing your chance of getting shingles.

Symptoms Of Eye Shingles

The symptoms of shingles around the eye may be different from the symptoms of eye involvement. Symptoms of shingles around the eye area may include:

Tingling on the face

Shorten the length of a shingles outbreak
Make shingles less painful
Reduce chances of persistent nerve pain after the rash resolves

In addition to these overall benefits, prompt treatment of eye shingles with antiviral medication can significantly reduce the risk of vision loss.

Without antiviral medication, 50% of ocular shingles patients will develop eye disorders compared with only 25% of patients who take the medication.

Its crucial to begin taking antiviral medication within 72 hours of the outbreak of the skin rash. It should be started as soon as possible after the rash starts, Rapuano says.

If your doctor diagnoses eye involvement with your case of ocular or facial shingles, you may also need topical eye drops. There are two main types of eye drops for shingles:

Corticosteroid eye drops Steroid drops can reduce the eye inflammation caused by shingles, Rapuano says. This lowers the chances of complications from shingles of the eye.
Pupil dilating eye drops Your eye doctor also may prescribe eye drops to keep the pupils open for pain relief due to an internal ocular inflammation caused by shingles.

What Should You Expect If You Get Shingles

Shingles can be a very painful condition. If you think you have the symptoms of shingles, see your healthcare provider right away. Starting antiviral medications early can ease your discomfort and end symptoms earlier.

A better approach to shingles is to take action and do what you can to lessen your risk of getting it. If you’ve never had shingles in the past, talk to your healthcare provider about getting the shingles vaccine. If youve never had chickenpox, talk with your healthcare provider about getting the chickenpox vaccine.

How Is Internal Shingles Treated

Even though shingles is a virus, this is a case where there are antiviral medications available by prescription. Thats why its important to see your doctor right away if you suspect you have shingles. Early treatment may reduce the risk of complications, like PHN. Serious complications require hospitalization.

Common antiviral medications for shingles include:

Depending on the location and severity of the shingles infection, steroids may also help. Anti-inflammatory medications like ibuprofen and pain-relieving medication such as acetaminophen or other prescription pain medication can help in easing pain experienced from shingles.

Where Does Shingles Come From

When you have chickenpox as a child, your body fights off the varicella-zoster virus and the physical signs of chickenpox fade away, but the virus always remains in your body. In adulthood, sometimes the virus becomes active again. This time, the varicella-zoster virus makes its second appearance in the form of shingles.

What Is Being Tested

Chickenpox and shingles are caused by an infection with the varicella zoster virus , a member of the herpes virus family. Varicella zoster virus tests detect either antibodies produced by the immune system in response to a VZV infection or detect the virus itself.

Tests for chickenpox and shingles may be performed to detect and diagnose a current or past infection with VZV. Most often, testing is not necessary to diagnosis an active infection because it can be made from clinical signs and symptoms, but in some people with atypical skin lesions, a diagnostic test helps to confirm the infection. In some people, especially organ transplant recipients and pregnant women, the tests may be used to diagnose a current infection or to determine whether or not they have developed immunity from prior infection or by vaccination.

Before the introduction and widespread use of a chickenpox vaccine in 1995, nearly everyone in the United States became infected by VZV by adulthood. While VZV is present in its latent form in many adults who were infected as children, according to the Centers for Disease Control and Prevention, the incidence of new cases of chickenpox has declined significantly. Two doses of the vaccine are about 98% effective in preventing the infection, and those who do become infected usually have milder symptoms.

What Are Chickenpox And Shingles Tests

These tests check to see if you are or have ever been infected with the varicella zoster virus . This virus causes chickenpox and shingles. When you are first infected with VZV, you get chickenpox. Once you get chickenpox, you can’t get it again. The virus remains in your nervous system but is dormant . Later in life, VZV can become active and can cause shingles. Unlike chicken pox, you can get shingles more than once, but it is rare.

Both chickenpox and shingles cause blistering skin rashes. Chickenpox is a highly contagious disease that causes red, itchy sores all over the body. It used to be a very common childhood disease, infecting nearly all children in the United States. But since a chickenpox vaccine was introduced in 1995, there have been far fewer cases. Chickenpox may be uncomfortable, but it’s usually a mild illness in healthy children. But it can be serious for adults, pregnant women, newborns, and people with weakened immune systems.

Shingles is a disease that only affects people who once had chickenpox. It causes a painful, burning rash that may stay in one part of the body or spread to many parts of the body. Nearly one-third of people in the United States will get shingles at some point in their lifetime, most often after the age of 50. Most people who develop shingles recover in three to five weeks, but it sometimes causes long-term pain and other health problems.

How Is Shingles Diagnosed

Is Shingles Contagious? How Do You Get Shingles?

As with most other diseases, doctors will typically review your symptoms first. Be sure to take note of how long youve experienced symptoms, what your exact symptoms are, and their severity. Doctors may suspect internal shingles if your symptoms involve more than your skin. They will often suspect eye or nervous system involvement based on the location of the shingles rash. However, if you have a painful rash along with a cough, severe headache, or abdominal pain, you may have a more serious complication of shingles.

Doctors may perform the following tests to confirm your diagnosis of shingles:

direct fluorescence antibody stain

Can You Get Shingles From The Covid

There have been a few reports of shingles happening in people who were vaccinated against COVID-19. The varicella-zoster virus was reactivated in these people.

A note from Cleveland Clinic

If youve had chickenpox, youre at risk of developing shingles later in life. Shingles causes a rash that is contagious and painful. The disease can have serious complications. The best thing you can do to reduce your risk is to get the shingles vaccine. The vaccines are safe and effective.

Can Shingles Be Prevented

There are 2 vaccines available to reduce the likelihood of developing shingles, Zostavax and Shingrix. If you are over 50, you can talk to your doctor about whether you need it. It is recommended for everyone over 60 and is given free of charge in Australia to people aged 70 to 79.

Vaccination will not guarantee that you will not get shingles, but it will reduce your chance of developing the condition. The vaccine used to protect against shingles is not the same as the vaccine used to protect against chickenpox. Read more about the chickenpox vaccine here.

Preventing The Virus Spreading

If you have the shingles rash, do not share towels or flannels, go swimming, or play contact sports. This will help prevent the virus being passed on to someone who has not had chickenpox.

You should also avoid work or school if your rash is weeping and cannot be covered.

Chickenpox can be particularly dangerous for certain groups of people. If you have shingles, avoid:

women who are pregnant and have not had chickenpox before as they could catch it from you, which may harm their unborn baby
people who have a weak immune system, such as someone with HIV or AIDS
babies less than one month old, unless it is your own baby, in which case your baby should have antibodies to protect them from the virus

Once your blisters have dried and scabbed over, you are no longer contagious and will not need to avoid anyone.

What Are The Possible Side Effects Of Shingrix

Shingles is on the Rise! Best Way to Protect Yourself

Studies show that Shingrix is safe. The vaccine helps your body create a strong defense against shingles. As a result, you are likely to have temporary side effects from getting the shots. The side effects might affect your ability to do normal daily activities for 2 to 3 days.

Most people got a sore arm with mild or moderate pain after getting Shingrix, and some also had redness and swelling where they got the shot. Some people felt tired, had muscle pain, a headache, shivering, fever, stomach pain, or nausea. Some people who got Shingrix experienced side effects that prevented them from doing regular activities. Symptoms went away on their own in about 2 to 3 days. Side effects were more common in younger people.

You might have a reaction to the first or second dose of Shingrix, or both doses. If you experience side effects, you may choose to take over-the-counter pain medicine such as ibuprofen or acetaminophen.

Guillain-Barré syndrome , a serious nervous system disorder, has been reported very rarely after Shingrix. There is also a very small increased risk of GBS after having shingles.

If you experience side effects from Shingrix, you should report them to the Vaccine Adverse Event Reporting System . Your doctor might file this report, or you can do it yourself through the VAERS websiteexternal icon, or by calling 1-800-822-7967.

If you have any questions about side effects from Shingrix, talk with your doctor.

If You Have More Than One Area Of Blisters What Can You Expect If You Go To The Hospital

Its important to note that most people with shingles dont need to be in a hospital, but if you do:

Youll be in a contact isolation room.
The door will be kept closed.
A sign on your door will remind people who have never had chickenpox or the vaccine not to enter.
The sign will also remind staff to wear gowns and gloves when entering the room.
