Shingles: Symptoms, Causes, and Treatment Options

About one in three people in the U.S. will get shingles at some point¹. This fact shows how common this viral infection is. It’s caused by the varicella-zoster virus, the same one that causes chickenpox. Shingles is a painful condition that can greatly affect someone’s life. But, with the right treatment and prevention, its effects can be lessened.

Shingles often shows up as a painful rash with blisters full of fluid on one side of the body. Other symptoms include pain, tingling, sensitivity to touch, and sometimes fever and fatigue². While shingles isn’t dangerous, it can lead to postherpetic neuralgia, a long-lasting pain condition³.

Key Takeaways

• Shingles is a viral infection caused by the varicella-zoster virus, the same virus that causes chickenpox.
• Shingles typically presents as a painful rash with fluid-filled blisters on one side of the body.
• Early treatment with antiviral medications can help shorten the duration and severity of the infection.
• Shingrix and Zostavax are two vaccines available to help prevent shingles and reduce the risk of complications.
• Shingles can recur, and individuals can experience the condition more than once.

What is Shingles?

Overview of the Viral Infection

Shingles, also known as herpes zoster, is caused by the varicella-zoster virus, the same virus that causes chickenpox⁴. After getting over chickenpox, the virus stays dormant in nerve cells. Later, it can wake up and travel to the skin, causing the shingles rash and pain⁴. This leads to inflammation of the nerves under the skin, showing up as symptoms.

About 1 in 3 people in the US will get shingles at some point⁵⁶. The risk goes up with age, with most cases happening in people over 50⁶. Those with weakened immune systems, like from cancer or HIV, or on certain drugs, are more likely to get it⁴.

The rash from shingles usually heals in 7-10 days and crusts over in 2-4 weeks⁴. But, some people may still feel severe pain, known as post-herpetic neuralgia, long after the rash goes away.

“The risk of spreading the virus causing shingles is low if the rash is covered; individuals should avoid scratching the rash and wash their hands frequently to prevent spreading shingles.”⁴

Symptoms of Shingles

Shingles is a viral infection caused by the varicella-zoster virus coming back to life. It usually starts with a burning or tingling feeling in one area of the body⁷. This is followed by a red, painful rash that looks like a stripe of blisters, often on the torso or face⁷.

People with shingles might also have fever, headache, sensitivity to light, and feel very tired⁷. The pain can be so bad it might seem like it’s coming from the heart, lungs, or kidneys⁷.

How shingles starts and how bad it gets can be different for everyone. Some might feel mild discomfort slowly, while others might have intense pain and blisters quickly⁸. If you have a weak immune system, you might get worse symptoms and complications⁷.

Knowing the early signs of shingles is key. Seeing a doctor quickly can help manage it and lower the chance of serious problems⁸. If you think you have shingles, see a healthcare professional for the right diagnosis and treatment.

Shingles can really affect someone’s life. Knowing the symptoms and getting medical help fast is important. This can help manage the condition and reduce the risk of serious problems⁷⁸⁹.

The Characteristic Shingles Rash

The hallmark sign of shingles is a distinctive shingles rash. It appears as a single stripe of fluid-filled blisters on one side of the body¹⁰. This single-sided rash often hits the torso, but can also strike the face, neck, or other spots¹¹. The rash stays within a specific area, supplied by one nerve, so it’s on just one side of the body¹⁰.

The rash turns into a clear stripe or band of blisters¹². Most folks with shingles see the rash heal in 3 to 4 weeks¹⁰. But, some might face complications like permanent skin color changes and scars¹².

It’s key to get medical help fast if the rash is on the face. This is a medical emergency¹⁰. Also, postherpetic neuralgia (PHN), a pain issue that lasts long, is more common in older folks¹². Taking antiviral meds within 3 days of the rash can lower PHN risk¹⁰.

In summary, the shingles rash is a unique, single-sided rash with fluid-filled blisters. It often shows up on the torso, face, or neck. Quick medical care and early treatment can help manage the rash and lessen complications¹⁰¹²¹¹.

When to Seek Medical Attention

Shingles is a viral infection that brings a painful rash and other symptoms. It’s not usually life-threatening, but seeing a doctor quickly is key in some cases¹³. Every year, over a million people get shingles, and about a third will have it at some point¹³. Knowing when to go to the doctor for shingles can stop serious problems and get you the right treatment.

Identifying Urgent Situations

If the shingles rash is near your eye, you should see a doctor right away¹³. Shingles near the eye can cause permanent eye damage if not treated. People over 50 or those with weak immune systems, like from cancer or HIV/AIDS, are more at risk and should get help fast¹³. A rash that covers a lot of skin and hurts a lot also means you should see a doctor quickly.

Getting to a doctor within 72 hours of the rash shows up is key¹⁴¹⁵. Early antiviral medicines work better. This can make the outbreak shorter and less severe, and lower the chance of getting long-term pain.

Shingles can happen to anyone who had chickenpox, at any age¹³¹⁴. If you think you might have shingles, call your healthcare provider for an exam and treatment¹³¹⁴¹⁵.

Causes of Shingles

Shingles is a painful skin rash caused by the varicella-zoster virus¹⁶¹⁷. This virus also causes chickenpox. After getting over chickenpox, the virus stays dormant in nerve cells¹⁶. Later, it can wake up and travel to the skin, causing the shingles rash and symptoms¹⁶.

The reason why the virus wakes up is not fully understood. But it often happens when the immune system is weak, like in older people or those with certain health issues¹⁶¹⁷¹⁸. Things that might make you more likely to get shingles include:

• Aging –¹⁶ Most people over 50 get shingles¹⁶¹⁸.
• Weakened immune system – Conditions like leukemia, lymphoma, and HIV, or certain medicines, can raise your risk¹⁷.
• Stress – Stress can wake up the virus¹⁷.

Even though we don’t know exactly why the virus comes back, the varicella-zoster virus is the main cause of shingles¹⁶¹⁷¹⁸.

“Shingles is caused by the reactivation of the varicella-zoster virus, the same virus that causes chickenpox. After a person recovers from chickenpox, the virus remains dormant in the body’s nerve cells and can reactivate years later, leading to the development of shingles.”

In summary, shingles happens when the varicella-zoster virus wakes up again. This can be because of a weak immune system, often from getting older, certain health issues, or some medicines¹⁶¹⁷¹⁸.

Risk Factors for Shingles

Anyone who has had chickenpox can get shingles because the virus stays in the body¹⁹. Some things make it more likely for the virus to wake up and cause shingles.

Getting older makes shingles more likely, especially for those over 50¹⁹. People with weak immune systems, like those with HIV or certain cancers, are more at risk¹⁹. Taking certain medicines that lower the immune system also raises the risk¹⁹.

Stress and infections can make the immune system weaker, making shingles more likely¹⁹. While most people who had chickenpox can get shingles, it’s rare to get it more than once¹⁹.

About one in three people in the U.S. will get shingles at some point²⁰. The risk goes up with age, especially for those 60 and older²⁰. Shingles is more common in women, making up nearly 60% of cases²⁰.

People with health issues like cancer, HIV, and diabetes are more likely to get shingles²⁰. Cancer patients are 40% more likely to get shingles²⁰. HIV patients are 12–17 times more likely²⁰. Diabetes patients are 1.6 times more likely²⁰.

Having a family history of shingles also raises the risk²⁰. People with shingles often have a family history of the condition²⁰.

Stress, negative life events, and feeling without purpose can also increase the risk of shingles²¹. Young people and children can get shingles too, not just older adults²¹.

Knowing the risk factors for shingles helps people take steps to prevent and manage it. By understanding these factors, individuals can work with their doctors to lower their risk and protect their health.

Complications of Shingles

Shingles is usually not a serious condition, but it can cause problems if not treated²². The CDC says 1 in 3 people will get shingles at some point²². These issues can include ongoing nerve pain, vision loss, and neurological problems.

Potential Complications to Watch For

Postherpetic neuralgia (PHN) is a common issue after shingles, causing long-lasting pain²². The CDC states 10–18% of people with shingles will face PHN, especially after age 50²². Shingles near the eyes can lead to painful eye infections, possibly causing vision loss²². About 10–20% of shingles cases affect the eyes, known as herpes zoster ophthalmicus (HZO)²².

Shingles can also cause neurological problems, like facial paralysis, hearing, or balance issues²³. Not treating shingles can lead to bacterial skin infections, often from Staphylococcus aureus²².

The shingles vaccine can greatly lower the risk of these complications, especially for older adults²³. It’s crucial to see a doctor quickly if you think you have shingles. Early treatment can prevent or manage these issues.

“Shingles complications become more common with age, and the risk of complications sharply increases after age 50.”²²

In summary, shingles can lead to serious complications, including nerve pain, vision loss, and neurological problems. Knowing the risks and getting medical help quickly can help prevent or manage these issues. This can reduce the long-term effects of this viral infection²²²³²⁴.

Prevention: The Shingles Vaccine

The best way to prevent shingles and its complications is through vaccination. In the United States, two shingles vaccines are available: Shingrix and Zostavax. According to the Centers for Disease Control and Prevention (CDC), the Shingrix vaccine is the recommended option for adults aged 50 and²⁵ due to its superior effectiveness.

Shingrix is a recombinant zoster vaccine that has been shown to be over 90% effective in preventing shingles and postherpetic neuralgia, a common and debilitating complication of shingles. The vaccine is administered in two doses, with the second dose given 2 to 6 months after the²⁵, and it can provide protection for at least seven years²⁶.

In contrast, the Zostavax vaccine, a live zoster vaccine, is less effective, with an average effectiveness of 41% in adults aged 70 to 79 and 18% in those 80 and older during the first 3 years following vaccination. As a result, Zostavax is no longer available in the U.S., and Shingrix is the recommended shingles vaccine²⁷²⁶.

The CDC recommends that adults aged 50 and older, as well as those 19 and older with weakened immune systems, should get the Shingrix vaccine to prevent shingles and its complications²⁵. However, it’s important to note that the Shingrix vaccine should not be administered during an acute episode of shingles or to individuals with a history of severe allergic reactions to any of its components²⁷.

While the shingles vaccine can be effective, it’s important to discuss your vaccination options with your healthcare provider, especially if you have any concerns or medical conditions that may affect your eligibility. Proper vaccination can significantly reduce the risk of developing shingles and its associated²⁵²⁶.

“The shingles vaccine is a crucial tool in preventing this debilitating condition and its long-term effects. By getting vaccinated, individuals can take an important step towards protecting their health and well-being.”

Diagnosis and Treatment Options

Identifying and Managing Shingles

Doctors usually spot shingles by looking for its typical signs, like the rash and pain²⁸. They might also take a sample to be sure it’s shingles²⁸. There’s no cure, but starting antiviral drugs early can help heal it faster and lessen complications²⁹. These drugs work best if taken within 72 hours of the rash showing up²⁹. Doctors might also suggest painkillers, creams, or other treatments for the symptoms.

Shingles can be tricky to diagnose, especially if it’s mild or the rash looks different²⁸. In these cases, doctors might use tests like PCR, Tzanck smears, or antibody tests to confirm it’s shingles²⁸. Getting it right is key because shingles can look like other skin issues like impetigo or insect bites²⁸.

Shingles is more common in people over 65³⁰. It comes back more often in those with weak immune systems, like people with cancer or HIV³⁰. Catching it early and treating it right is important to lessen symptoms and prevent problems like PHN or HZO²⁹. If you have HZO, see an eye doctor right away²⁹.

There’s no cure for shingles, but treatment can really help²⁹. Using antiviral drugs, managing pain, and getting support can ease symptoms and help heal faster²⁹. Starting antiviral treatment in the first three days is key to its effectiveness²⁹.

“Shingles is a painful and potentially debilitating condition, but with proper diagnosis and treatment, most people can manage their symptoms and minimize the risk of complications.”

Knowing how to diagnose and treat shingles helps people take charge of their health and work with doctors for better care²⁹²⁸³⁰.

Self-Care Tips for Shingles

There are steps you can take to help ease shingles symptoms, besides medical treatment. Shingles self-care is key to getting better.

One good way to ease the discomfort is by taking cool baths. The cool water can soothe the itching and pain from the rash³¹. Applying cool compresses to the rash can also help calm it down³².

It’s also vital to manage your stress levels. Stress can make shingles symptoms worse. Try relaxation methods like meditation, deep breathing, or doing things you enjoy³³.

You can use over-the-counter pain relievers like ibuprofen or naproxen for pain³¹. But, avoid alcohol and heavy machinery when taking painkillers for shingles³¹.

If your symptoms don’t get better or get worse, see a healthcare provider. Call your doctor if you get a rash like shingles, if the pain isn’t managed, or if pain lasts for 3 to 4 weeks³¹.

Using these self-care tips can help you feel better and support your healing. Always get medical help and follow a treatment plan for shingles³²³³.

“Shingles is considered to be one of the most painful medical conditions humans experience.”³³

Preparing for a Doctor’s Appointment

When you’re getting ready to see a doctor for shingles, being prepared is key³⁴. Arriving 10–15 minutes early helps you avoid feeling rushed³⁴. It’s also important to share your family’s health history with your doctor³⁴. Make sure you have a list of your medications ready³⁴. Tracking devices can give your doctor a clear picture of your health.

What to Expect and How to Prepare

³⁴ Let the doctor’s office know if you need special arrangements ahead of time³⁴. Check if your insurance covers the doctor’s office to avoid unexpected costs³⁴. Bring any past test results, like mammograms or blood tests, with you³⁴. Having your current and past medications, along with the bottles, helps your doctor understand your health better.

1. ³⁴ Taking notes during your visit helps you remember what your doctor said and what you need to do next.
2. ³⁴ Write down any questions or concerns you have before you go to make sure they get answered.
3. ³⁴ Keep emergency contact info handy for any sudden health issues.
4. ³⁴ Having someone with you can make the appointment easier and help you communicate better with your doctor.
5. ³⁴ List all your past and current doctors to help coordinate your care.
6. ³⁴ Share any allergies, past surgeries, health conditions, and current symptoms with your doctor.
7. ³⁴ Plan your route to the doctor’s office to make sure you arrive on time.
8. ³⁴ Health trackers can show your daily habits and health patterns to your doctor.
9. ³⁴ Bringing something to do in the waiting room, like a book or puzzle, can be helpful.
10. ³⁴ Use a device to take notes during your appointment so you don’t forget important advice or plans.

³⁵ You can book an appointment online or call 877.463.2010³⁵. Arrive 15 minutes early for your first visit, 30 minutes if it’s your first time³⁵. Most insurances are accepted, and you’ll need to pay at the time of service.

³⁶ Starting shingles medication early can make symptoms less severe and shorter³⁶. Some antivirals need to be taken several times a day³⁶. Painkillers for shingles should be closely watched to prevent misuse.

³⁶ Caregivers can prevent spreading infections by washing hands often and covering the rash³⁶. The rash from shingles usually heals in about 10 days, stopping the spread of the virus³⁶. Stress and pain are linked during recovery from shingles.

Doing calming activities can help lower stress³⁶. Social support is key to getting better from shingles³⁶. Shingles isn’t contagious, but it can give chickenpox to those not immune before the rash heals³⁴³⁵³⁶.

Shingles Vaccine: Zostavax vs. Shingrix

In the U.S., two vaccines fight shingles: Zostavax and Shingrix. The CDC picks Shingrix as the top choice because it works better³⁷.

Shingrix is over 90% effective in stopping shingles and nerve pain in people 50 and up with strong immune systems³⁸. For those with weaker immune systems, it’s 68%-91% effective³⁸. Zostavax, on the other hand, has a 70% success rate in people 50 to 69 and 51% in those over 60³⁹.

Shingrix is advised for people 50 and older, even if they’ve had shingles or got Zostavax before³⁷. It also helps those with weaker immune systems³⁸.

Zostavax is no longer used for shingles in the U.S. since 2018. Shingrix is now the top choice by the ACIP for its strong evidence and results³⁷.

Shingrix costs about $167 per dose, while Zostavax is around $278, affecting by insurance³⁹. Medicare Part D covers Shingrix fully in 2023, and Medicaid may too, so check with your insurer³⁸. There are also programs for those who can’t afford Shingrix³⁸.

Shingrix might cause some side effects like a sore arm or mild pain, but these usually go away in 2 to 3 days³⁸. Serious issues are very rare, happening to about 1 to 2 people per million doses³⁸.

To sum up, Shingrix is the top choice for shingles prevention because it’s more effective. It’s good for more people, including those with weaker immune systems. Even though it costs more at first, Shingrix is covered by insurance and programs, making it more accessible³⁸³⁹³⁷.

Conclusion

Shingles is a painful viral infection caused by the varicella-zoster virus, the same virus that causes chickenpox⁴⁰. It mostly affects people over 50, as their immune system gets weaker⁴⁰. While it’s not deadly, it can cause long-term nerve pain and vision issues⁴¹.

Getting vaccinated, starting antiviral treatment early, and taking care of yourself can help manage shingles⁴⁰. The German STIKO suggests vaccination for people over 60, and for those over 50 with weak immune systems or chronic diseases⁴⁰. In the U.S., the Shingrix vaccine is over 90% effective in preventing shingles, offering protection for at least 4 years⁴¹.

Research is still looking into how stress affects shingles, but it’s clear that quick medical help is key for those at high risk⁴⁰. Knowing about symptoms, causes, and treatments helps people take steps to prevent and manage shingles⁴⁰⁴¹.
