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.
Recovery From Eye Shingles
Recovery time varies by patient and the specific case, Rapuano says. If the inflammation is mild and the treatment is pretty aggressive, then symptoms may start getting better within days, he says.
At some point, the optician may try to slowly wean the patient off steroids. But a recurrence of inflammation may signal a need to keep using steroid eye drops.
Many patients will need to be on low-dose steroids for years, if not forever, Rapuano says.
Whos At Risk For Shingles
Anyone who has ever had chickenpox can get shingles, but the risk increases with age. People older than age 60 are up to 10 times more likely to get shingles than younger people. Other factors that increase your risk include:
- Some cancer medicines
- A weak immune system from illnesses such as cancer or HIV
A quarter of adults will develop shingles at some point, and most are otherwise healthy.

How Do Shingles Reactivate In The Nervous System
The shingles virus stays dormant in the nerve tissues. If your immune system grows weaker, the virus reactivates.
As the virus becomes active, it spreads through the spinal cord nerves to the skin. These nerves convey messages of pressure, itching, and pain.
These messages transfer from the spinal cord to the brain. Once the varicella-zoster virus gets to the nerve endings, it shows up as a skin rash.

Is Shingles Contagious
Yes, but not in the way you may think. Your shingles rash will not trigger an outbreak of shingles in another person, but it can sometimes cause chickenpox in a child. People whove never had chickenpox, or the vaccine to prevent it, can pick up the virus by direct contact with the open sores of shingles. So keep a shingles rash covered and avoid contact with infants, as well as pregnant women who have never had chickenpox or the varicella vaccine and people who may have weak immune systems such as chemotherapy patients.

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.

How Is Shingles Diagnosed
If you have symptoms of shingles, especially if they involve your face, see your doctor or ophthalmologist right away.
Doctors can usually diagnose a shingles rash by performing a physical exam. Your doctor can also take a scraping of your skin rash and send it to a lab for examination under a microscope.
Its particularly important to seek treatment if you have a compromised immune system. Early treatment can help cut down on your chances for serious complications.
Shingles will have to run its course, but quite a few treatment options are available. These include:
- antiviral drugs

What Causes Ramsay Hunt Syndrome
Ramsay Hunt syndrome occurs when the varicella-zoster virus reactivates in the facial nerve, which is the cranial nerve that affects your face, tongue and inner ear. The varicella-zoster virus is the same virus that causes chickenpox and shingles.
If you had chickenpox as a child, the virus can remain inactive in your nerves for years. Shingles occurs when the previously dormant varicella-zoster virus reactivates. The virus travels down your nerve fibers into your skin, causing painful sores. The virus sometimes develops into Ramsay Hunt syndrome, affecting your facial nerve. Researchers aren’t sure why the virus sometimes involves the facial nerve.
What Are The Symptoms
The first sign of shingles is often burning, sharp pain, tingling, or numbness in your skin on one side of your body or face. The most common site is the back or upper abdomen. You may have severe itching or aching. You also may feel tired and ill with fever, chills, headache, and upset stomach or belly pain.
One to 14 days after you start feeling pain, you will notice a rash of small blisters on reddened skin. Within a few days after they appear, the blisters will turn yellow, then dry and crust over. Over the next 2 weeks the crusts drop off, and the skin continues to heal over the next several days to weeks.
Because shingles usually follows nerve paths, the blisters are usually found in a line, often extending from the back or side around to the belly. The blisters are almost always on just one side of the body. Shingles usually doesn’t cross the midline of the body. The rash also may appear on one side of your face or scalp. The painful rash may be in the area of your ear or eye. When shingles occurs on the head or scalp, symptoms can include headaches and weakness of one side of the face, which causes that side of the face to look droopy. The symptoms usually go away eventually, but it may take many months.
In some cases the pain can last for weeks, months, or years, long after the rash heals. This is called postherpetic neuralgia.

Risk Factors For Shingles
Once youve had chickenpox as a child, youre at risk of getting shingles later in life. The virus stays dormant, or asleep, in your body. It hides out in nerve cells near your spinal cord, but it can become active again when youre older.
Youre at increased risk of getting shingles if you:
- had chickenpox as a child
- are age 50 or older because your immune system weakens as you age
- have a weakened immune system because of a disease like cancer, HIV infection, or AIDS
- take medicine that weakens your immune system, such as chemotherapy or radiation for cancer, or stops your body from rejecting a transplanted organ
Shingles is especially serious in some groups of people, including:
What Does A Mild Case Of Shingles Look Like
Not everyone with shingles will develop a blistering rash. A mild case of shingles may include a red rash without blisters. The shingles rash and blisters are distinct characteristics of the illness. Mild cases of shingles do not usually cause headaches, fever, or fatigue.
Whether mild or severe, pain is the most common symptom of shingles. Most people describe a deep burning, throbbing, or stabbing sensation. The pain usually subsides within 30 days.

When To See A Doctor
If you suspect you have shingles, you should see a doctor right away. You can then begin appropriate treatment that will help relieve your symptoms, speed your recovery, and lower your risk of complications. This is especially important if you:
- Are over age 60
- Have a condition that has caused you to have a weakened immune system, such as HIV
- Take medication that may diminish your bodyâs immune response
- You share a home with someone who has a weakened immune system
- The rash is on your face: Blisters near your eye could lead to serious eye damage or even cause you to lose sight in that eye.
Shingles Doctor Discussion Guide
If while youâre dealing with shingles you experience any of the following, let the doctor whoâs treating you know right away:
- You arenât getting relief from the pain with treatment.
- The pain doesnât go away after three to four weeks.
- The rash spreads beyond the initial area.
- You begin to have symptoms of a secondary infection, such as a very high fever, chills, and severe headache.
Your healthcare provider will help you determine the right treatment for you. This may include antiviral drugs, antidepressant medications, and pain medications.
Am I Contagious If I Have Shingles
Shingles cannot be passed from one person to another. But someone who has never had chickenpox can contract VZV from a person with active shingles. They would then develop chickenpox, not shingles.
Only direct contact with fluid from shingles blisters can transmit the virus. Keep shingles blisters covered with a fluid absorbent dressing to prevent others from contracting the virus.

Is It Different Than Herpes Zoster
This disease is much different than shingles, although the relation in symptoms may cause superficial confusion to the untrained eye and they werent differentiated until the 19th century. Shingles is a viral infection. Aside from being caused by a virus, it is a prolonged process whereby you dont immediately happen upon contact with the particle, but after the duration of inactivity for the random activation. differences existing on a microscopic level meaning antibiotics will not suffice treatment. Therefore, it is crucial to visit a licensed physician rather than self diagnose via pictures you find online.
Other Health Problems Due To Shingles
Some people develop other health problems after the shingles rash clears, which include:
Postherpetic neuralgia : This is the most common. Occurring where you had the rash, PHN can cause constant tingling, burning, and pain. For others, the pain comes and goes.
Whether the pain is constant or intermittent, it can go on for a long time. You can have PHN for months, years, or the rest of your life. There is no way to know how long it will last.
The pain caused by PHN can become so severe that it interferes with your life, making everyday activities painful. A musician may no longer be able to play an instrument. Some people cannot walk comfortably. It may be difficult to bathe or get dressed. You may have trouble sleeping.
How to prevent PHN: If you have shingles, you can greatly reduce your risk of PHN by getting treated for shingles within 3 days of developing the rash.

What Is Postherpetic Neuralgia
In some instances, people whove had shingles may experience postherpetic neuralgia , in which pain persists well after the blisters go away. This happens because the shingles-damaged nerves continue to send pain signals to the brain.
There are several factors that can lead to postherpetic neuralgia. Anything that depresses immunity can increase your risk, says Dr. Oaklander.
She adds: The severity of postherpetic neuralgia gradually eases over time in everyone, but the rate of resolution can vary. As you get older, your postherpetic neuralgia typically lasts longer and longer. Senior citizens, who are the most at risk for zoster, have substantial risk of postherpetic neuralgia lasting over a year, and sometimes for the rest of their lives.
If you have a lot of pain before the rash, it puts you at much higher risk for postherpetic neuralgia, adds Joseph Safdieh, MD, professor of neurology at Weill Cornell Medicine in New York City.

Are There Common Shingles Nerve Pathways Maps
The cranial nerves exit directly from the brain. On the other hand, the spinal nerves exit from the spinal cord. Everyone has 31 pairs of spinal nerves and 12 pairs of cranial nerves. Each skin area is innervated by one of these nerves.
The most common nerve path that shingles follow is the thoracic dermatome. The thoracic dermatome is a band of skin supplied by sensory nerves exiting from the spine in the thoracic region.
The rash associated with shingles typically starts as a band of raised red bumps on one side of the neck and chest and often wraps around the side to the back.
A shingles rash can also occur along the path of other sensory nerves, such as cranial and cervical. The rash associated with shingles on these nerve paths is typically less severe than the thoracic dermatome rash.

What is shingles?
The same virus that causes chickenpox causes shingles. Its called the varicella zoster virus .
VZV stays dormant in your body even after you recover from chickenpox. The chickenpox virus can reactivate years or even decades later, but its not understood why.
When this happens, a person will develop shingles. Recognizing the early symptoms is important because it can be a painful condition with severe complications.
state that almost 1 in 3 people in the US will develop shingles in their lifetime. But some people are more likely to develop shingles than others.
It is that half of all cases of shingles occur in people aged 60 years and older.
Other groups prone to developing shingles include:
- people who have had organ transplants
- people experiencing a lot of stress

What virus causes vestibular neuritis?
The most common causes of vestibular neuritis and labyrinthitis are viral infections, often resulting from a systemic virus such as influenza or the herpes viruses, which cause chickenpox, shingles and cold sores.
Can You Get Shingles In The Eye
If you have the shingles rash around your eye, or even felt a shingles-like pain in the area, it’s important to see an eye doctor right away.
Shingles in the eye tends to show up either inside the eyelid or on the surface of the eyeball. The cornea is a common place to see shingles, says Rebecca Taylor, MD, an ophthalmologist with Nashville Vision Associates in Tennessee. Its the clear domed tissue that you put contacts on.
Shingles also often appears on the conjunctiva, she adds, which is the clear tissue that covers the whites of your eye and the inside of your eyelid.
Theres also a pattern in the rash to look out for, says Dr. Taylor. If you have blisters on the tip of your nose, thats a strong predictor of there being inflammation inside the eye.
Community Eye Health
Steroid eye drops and lubricating tears may also be prescribed. You should also have regular eye exams in the months and years after the episode.
