Can Postherpetic Neuralgia Be Prevented
The Food and Drug Administration has approved a shingles vaccine, which can reduce your chance of getting shingles and PHN. The recombinant herpes-zoster vaccine is recommended to prevent shingles in adults ages 50 and older. The vaccination is given in two doses, two to six months apart. The two-dose vaccine is 90% effective at preventing shingles and PHN. Protection lasts at least for four years after you get vaccinated.
If you have never had chickenpox or have children who have never had chickenpox, getting the chickenpox vaccine can help prevent getting this infection in the first place. If you never get chickenpox, you will not have the varicella-zoster virus in your body and will not get shingles or PHN.
Who Should Not Get Shingrix
You should not get Shingrix if you:
- Have ever had a severe allergic reaction to any component of the vaccine or after a dose of Shingrix.
- Currently have shingles.
- Currently are pregnant. Women who are pregnant should wait to get Shingrix.
If you have a minor illness, such as a cold, you may get Shingrix. But if you have a moderate or severe illness, with or without fever, you should usually wait until you recover before getting the vaccine.
How Do Dermatologists Treat Shingles
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:
Pain: Medication that you can buy without a prescription can help, such as:
If you have severe pain, your dermatologist may prescribe a medication that reduces inflammation, such as a corticosteroid.

What Causes Postherpetic Neuralgia
Postherpetic neuralgia results from damage to nerve fibers during shingles infection. The nerve fibers at the skin in the affected area send exaggerated pain signals to your brain. Postherpetic neuralgia means nerve pain after herpes. Shingles is also called herpes zoster.
Shingles is caused by the varicella-zoster virus, the virus that causes chickenpox. Once youve had chickenpox, the virus remains in your body for your entire life, but is dormant or silent for years. When the virus becomes reactivated, it causes shingles. A certain percentage of people who get shingles develop PHN.
Facial Pain And Eye Damage
Between 10% and 15% of the time, shingles affects the trigeminal gangliona triple-branched nerve that provides sensation to structures in the face. The medical term for head or facial pain due to shingles is “painful trigeminal neuropathy attributed to herpes zoster.”
Specifically, the trigeminal ganglion involves the eye the cheek and the mandibular branch . Of these, the ophthalmic branch is the one most commonly affected by herpes zoster.
According to the American Academy of Ophthalmology , 25% of the 300,000 to 500,000 cases of shingles that occur each year are herpes zoster ophthalmicus .
HZO can affect any part of the eye, from the optic nerve to the conjunctiva . Without antiviral treatment, almost half of people who have shingles near the eye will experience eye damage or even lose an eye, so it’s vital to see an ophthalmologist immediately.

When Should I See A Doctor Because Of The Side Effects I Experience From Shingrix
Shingrix causes a strong response in your immune system, so it may produce short-term side effects. These side effects can be uncomfortable, but they are expected and usually go away on their own in 2 or 3 days. You may choose to take over-the-counter pain medicine such as ibuprofen or acetaminophen. Contact your healthcare provider if the symptoms are not improving or if they are getting worse.
In clinical trials, Shingrix was not associated with serious adverse events. In fact, serious side effects from vaccines are extremely rare. For example, for every 1 million doses of a vaccine given, only one or two people might have a severe allergic reaction. Signs of an allergic reaction happen within minutes or hours after vaccination and include hives, swelling of the face and throat, difficulty breathing, a fast heartbeat, dizziness, or weakness. If you experience these or any other life-threatening symptoms, see a doctor right away.

Why Does Shingles Appear Mostly On One Side Or In One Area Of Your Body
The virus travels in specific nerves, so you will often see shingles occur in a band on one side of your body. This band corresponds to the area where the nerve transmits signals. The shingles rash stays somewhat localized to an area. It doesnt spread over your whole body. Your torso is a common area, as is your face.
First Signs And Symptoms Of Shingles
Among the systemic symptoms that may appear in the first few days of the prodromal stage of shingles are:
- Pain in a specific, localized area of the body
- Sensitivity to light
The most telling first symptom of shingles typically is the pain. Often excruciating, the discomfort has been described as burning, stinging, tingly, prickly, itchy, numbing, achy, or shooting. It can be persistent or intermittent, but will always be limited to one side of the body.
Because the pain from shingles is localized, it can be mistaken for other conditions depending on where it’s focused.
For example, a stabbing or persistent pain on one side of the lower back may mistakenly be attributed to sciatica or a kidney problem. Shingles pain around the lips could suggest a cold sore coming on, while pain focused on the eye or ear might seem like the start of a migraine.

What Is Postherpetic Neuralgia
Postherpetic neuralgia is a complication of shingles infection . Shingles is caused by the reactivation of the varicella-zoster virus, which is the same virus that causes chickenpox.
Shingles causes a painful, blistering rash and other symptoms. The rash most commonly occurs in a band pattern on one side of your body, usually on your trunk . The rash turns into blisters. As the rash/blisters go away, pain may remain. When pain remains, the condition is called postherpetic neuralgia.
Who Is At Risk Of Getting Postherpetic Neuralgia
Factors that increase the risk of developing postherpetic neuralgia include:
- Older age: The chance of developing postherpetic neuralgia increases with age. If youre older and develop shingles, youre more likely to develop PHN and have longer lasting and more severe pain than a younger person with shingles. About 10 to 13% of people over age 50 who have had shingles will get PHN. People under age 40 rarely get PHN.
- Weakened immune system: Your immune system weakens as you get older, which allows the inactive varicella-zoster virus to become active again and cause shingles in some people. Medical conditions that can weaken your immune system include cancer, chronic infectious diseases , being an organ transplant recipient or taking medications that weaken your immune system .
- Severity of your shingles: If you have a severe rash, you have a greater chance of PHN.
- Painful, itchy or tingly feeling before shingles rash: If you had these symptoms in an area of skin a few days before your shingles rash broke out, you are at higher risk of PHN.
- Waiting to see your healthcare provider after shingles rash: If you wait longer than three days after your rash appeared missing the window to receive antiviral drugs you have an increased chance of PHN.

What Do Shingles Scabs Look Like
Shingles scabs develop when your blisters dry up. The blisters that form on the rash usually start to scab within 7 to 10 days. These scabs are usually dry and flat and can be red, brown, or yellowish in color.
Since shingles blisters affect just one side of the body, the scabs will only appear on one side as well. This is different from most other skin conditions, which typically affect both sides of the body.
Other common skin disorders might cause peeling or white patches . Shingles scabs usually dont have these characteristics.
The following images show what shingles scabs look like:
Can I Give Shingles To Others
No one can catch shingles from you. But the virus can be spread to a person who has never had chickenpox. The virus lives in the blisters that shingles causes. It can be spread until the blisters are completely healed. If you have blisters that have not crusted over yet, you should stay away from:
- Anyone who has never had chickenpox
- Babies under 12 months old
- Very sick people
Tell your doctor if you live with children who have not had chickenpox. They may need to be vaccinated.

What Is Shingles And Who Can Get It
Shingles is another name for a condition called herpes zoster. It causes a painful rash. You can only get shingles if you had chickenpox in the past.
After you have chickenpox , the virus that causes it stays in your body, in certain nerve cells. Most of the time your immune system keeps the chickenpox virus in these cells. As you get older or if your immune system gets weak, the chickenpox virus may escape from the nerve cells and cause shingles.
Most people who get shingles are more than 50 years old or have a weak immune system. For example, you might get shingles if you have cancer, take medicines that weaken your immune system or have the virus that causes AIDS .
How Is Postherpetic Neuralgia Diagnosed
Postherpetic neuralgia is usually diagnosed based on your symptoms, history of having shingles and physical exam. If youve had a recent case of shingles and have pain in the area where the shingles rash once was, you likely have PHN. Your provider may want to make sure your pain is not caused by something else, but in most cases, no other tests are needed.

How Can I Take Care Of Myself
- Take a pain-relief medicine such as acetaminophen. Take other medicine as prescribed by your healthcare provider.

- Try not to let clothing or bed linens rub against the rash and irritate it.
- You develop worsening pain or fever.
- You develop a severe headache, stiff neck, hearing loss, or changes in your ability to think.
- The blisters show signs of bacterial infection, such as increasing pain or redness, or milky yellow drainage from the blister sites.
- The blisters are close to the eyes or you have pain in your eyes or trouble seeing.
- You have trouble walking.
Are Shingles Contagious Yes Or No
If you had chickenpox when you were a child, you are at risk for shingles. Shingles occurs when the varicella-zoster virus that caused your chickenpox re-emerges after lying dormant in your nerve cells from the time of your original illness. When this occurs, you are contagious, but you can’t give someone shingles.

How Long Does Postherpetic Neuralgia Last
Postherpetic neuralgia can last for weeks, months, or in some people, years after the shingles rash goes away. In most people, shingles pain goes away in one to three months. However, in one in five people, pain lasts more than one year.
The pain from PHN can be so severe in some people that it disrupts their life. Researchers dont know why some people have severe or long-lasting pain and others do not.
You Cannot Get Shingles From Someone With Chickenpox
You cannot get shingles from someone with shingles or chickenpox.
But you can get chickenpox from someone with shingles if you have not had chickenpox before.
When people get chickenpox, the virus remains in the body. It can be reactivated later and cause shingles if someone’s immune system is lowered.
This can be because of stress, certain conditions, or treatments like chemotherapy.

- The rash is typically affects just one area on one side of the body or face.
- Treatment that is started as soon as possible helps reduce the severity of the disease.
The Stages Before And After Rash Development
The most well-known symptom of shingles is a severe skin rash. However, before any signs of blisters, you may feel as if you’re only coming down with the flu.
You may experience chills and fever, as well as intense pain. It’s not until a few days later that a rash finally joins these shingles symptoms, with clusters of tiny, pimple-like blisters progressing quickly once they appear.
If you’re familiar with the signs and symptoms of shingles, you’ll be able to recognize what’s going on, get a diagnosis quickly, and deal with it without delay. Doing so makes you less likely to develop complications, such as nerve issues or bacterial skin infections.

Tingling Pain Or Numbness
During the first stage of shingles, before anything appears on your skin, a particular area of your body may begin to feel different. “When a shingles outbreak is starting, you may feel itching, burning, or pain,” Kim says. Often you will feel this on only one side of your body.
The initial signs of shingles may feel different for each person. In some cases, shingles can cause intense sensitivity, making it painful to even wear clothes over your skin, while in other cases, your skin may feel numb.
Appearance Of The Shingles Rash
The eruptive stage of shingles begins a few days later. This is when a rash appears.
The skin in the area of the prodromal pain caused by shingles will often be sensitive to the touch and reddish in appearance. As these symptoms get worse, it may begin to feel like a sunburn.
Within three to five days of the initial pain, a few tiny pimple-like spots appear and quickly multiply into clusters, forming a rash that feels prickly to the touch.
From there, sometimes within hours, the pimples develop into water-filled blisters, or vesicles, that then consolidate into larger blisters. Often, redness and swelling accompany the rash.
The shingles rash looks very much like the chickenpox rash, with a key difference: Chickenpox blisters are widely scattered over the entire body. With shingles, the rash almost always occupies a finite strip of skin.
Ultimately, the pain of shingles may get so excruciating that simply grazing the skin with clothing can set off what feels like an electric shock.

What Causes Shingles
Shingles is caused by reactivation of the varicella zoster virus that causes chickenpox. After the initial infection, the virus remains dormant or inactive in the nerves for many years. About 1 in 3 adults who had chickenpox develop shingles later in life due to reactivation of the virus.
Risk factors for getting shingles includes:
How Does It Occur
If you have had chickenpox, you are at risk for later developing shingles. After you recover from chickenpox, the chickenpox virus stays in your body. It moves to the roots of your nerve cells and becomes inactive . Later, if the virus becomes active again, shingles is the name given to the symptoms it causes.
What exactly causes the virus to become active is not known. A weakened immune system seems to allow reactivation of the virus. This may occur with normal aging, immune-suppressing medicines, or another illness, or after major surgery. It can also happen as a complication of cancer or AIDS or treatment of these illnesses. Chronic use of steroid drugs may trigger shingles. The virus may also become active again after the skin is injured or sunburned. Emotional stress seems to be a common trigger as well.
