Let's learn about Postherpetic Neuralgia, the severe nerve pain that occurs after shingles.

Have you ever had 'herpes' or 'shingles' as we call them? Do you know someone who has? Anyone who has experienced it knows the pain and discomfort it can cause. But sometimes, even after the herpes blisters have completely healed, there is still severe pain in the affected area that can last for months, even years. That's what we call Postherpetic Neuralgia (PHN). This is a very annoying and life-threatening condition. So let's find out more about it.

Simply put, what is Postherpetic Neuralgia (PHN)?

This is a common complication of shingles. It occurs as persistent pain in the same area as the blisters and rash that appear on the skin after herpes has healed.

Do you remember chickenpox as a child? The same virus that causes chickenpox (varicella-zoster virus) can become active again in our bodies years later and cause herpes zoster. Although not everyone who gets herpes will develop it, about one or two out of 10 people will develop PHN.

This pain can be very debilitating, physically, mentally, and emotionally. So the first and most important step is to talk to your doctor about it. Then, together, you can come up with a good plan to manage this pain.

What are the symptoms of this condition?

These symptoms can start at the same time as the herpes rash. Or they can appear weeks or even months after the rash has completely healed. The main symptoms are:

• Pain: This pain is experienced differently by each person. While some may simply feel like a sore spot , others may feel like a burning sensation . Others may feel like a sharp stabbing , stabbing , or electric shock . This pain may be constant or come and go.
• Itchy skin: There may be itching in the area of ​​pain.
• Numbness: There may be a decrease in sensation or complete numbness in the area.
• Skin sensitivity: Sometimes the skin becomes incredibly sensitive. Even the slightest touch of clothing or a gust of wind can cause unbearable pain. This pain can be triggered by even a slight change in temperature.

Why is this happening? What is the reason?

Simply put, PHN is caused by the herpes virus damaging your nerve fibers. Think of your body as a network of electrical wires. These nerves send signals to your brain. When these 'wires' are damaged by the herpes virus, they start sending incorrect, much stronger pain signals to your brain. That's why you feel pain all the time for no reason.

Doctors still can't figure out exactly why some people who actually get herpes develop this condition and others don't.

Who is at higher risk of developing this?

Some people are more likely to develop PHN. Let's take a look at who they are.

Other problems that can arise from long-term pain

Living with pain all day long is not easy. It can affect many aspects of your life.

• Depression: Feeling sad and depressed when you are in constant pain can lead to depression .
• Constant fatigue: You may feel tired and exhausted all the time.
• Insomnia: You may not be able to sleep well at night due to the pain.
• Appetite: The desire to eat may decrease.
• Difficulty concentrating: It can be difficult to focus and stay focused on something.

If this pain is interfering with your daily life, never hesitate to ask for help. You may also find it helpful to seek advice from a mental health professional .

How do doctors diagnose this?

Most of the time, a doctor can tell if you have PHN by:

• By listening carefully to your symptoms .
• By asking about your medical history , especially how you developed herpes.
• By doing a physical exam .

Very rarely, some people can develop herpes without a rash. In such cases, or if it is a rare type that affects the throat, the doctor may order blood tests or other imaging tests.

How is it treated?

Although there is no cure for PHN, there are effective treatments that can help control the pain and make your life easier. Your doctor will likely prescribe one of these medications:

• Tricyclic antidepressants: For example, drugs like `(nortriptyline).` Although these are used for depression, they are also very helpful in controlling nerve pain.
• Antiseizure medications: Drugs like `(pregabalin)` or `(gabapentin)`. These are also very effective in controlling nerve pain.
• SNRI drugs: Drugs such as ``(duloxetine)`` are also used for this purpose.
• Sodium channel blockers: Drugs like `(carbamazepine)`.
• Skin patches or ointments: Applying creams or patches containing `(Lidocaine)` or `(Capsaicin)` to the skin can temporarily relieve pain.

Sometimes it can take a while to find the right treatment for you. If one medication doesn't work, you may need to try another. Sometimes you may need to use several medications together. If your symptoms don't improve, tell your doctor.

Other treatments for severe cases

For severe pain that lasts a very long time and doesn't respond to typical medications, your doctor may recommend treatments like these:

• Nerve blocks: An anesthetic drug is administered through an injection into the nerve that is causing the pain.
• Epidurals: Injection of medication into the spinal cord.
• Spinal cord stimulation: Pain control by sending electrical signals to the spinal cord using a small device.

Can't this situation be prevented?

Yes, you can! The best and most effective way to prevent postherpetic neuralgia is to get the shingles vaccine . This vaccine significantly reduces both your risk of developing shingles and the long-term nerve pain it can cause. Adults are usually given two doses of the vaccine, spaced a few months apart.

In addition, it is important to remember about the chickenpox vaccine . If you or your children have never had chickenpox, getting this vaccine can prevent the chickenpox virus from entering the body. A person who has never had chickenpox will not develop herpes or PHN later.
