Shingles, also known as herpes zoster, is a viral infection caused by the varicella-zoster virus (VZV). The same virus that causes chickenpox. After a person has chickenpox, the virus can remain dormant in the body's nerve cells.
Years or decades later, the virus can reactivate and travel along the nerve pathways to the skin, causing a painful rash and other symptoms. Shingles can affect anyone who has had chickenpox, regardless of their age or health status. However, it is most common in people over the age of 50 and those with weakened immune systems.
If you are experiencing a painful rash, especially if it is accompanied by other symptoms such as fever, chills, or fatigue, it is important to see a doctor immediately. Early diagnosis and treatment of shingles can help reduce the risk of complications and shorten the duration of the illness.

Shingles can be a serious illness, but it is important to know that it can be prevented and treated. If you are experiencing a painful rash, especially if it is accompanied by other symptoms such as fever, chills, or fatigue, it is important to see a doctor immediately.
Reactivation of dormant virus
The varicella-zoster virus (VZV) can remain dormant in the body's nerve cells after a person has chickenpox. Years or decades later, the virus can reactivate and travel along the nerve pathways to the skin, causing a painful rash and other symptoms.
- Age-related decline in immunity: As people age, their immune system weakens, making them more susceptible to reactivation of the VZV.
- Certain medical conditions: People with weakened immune systems, such as those with cancer, HIV/AIDS, or organ transplants, are also more likely to experience reactivation of the VZV.
- Stress: Physical or emotional stress can trigger reactivation of the VZV.
- Medications: Some medications, such as corticosteroids and chemotherapy drugs, can suppress the immune system and increase the risk of VZV reactivation.
Reactivation of the VZV does not always lead to shingles. In some cases, the virus may simply cause a mild rash or no symptoms at all. However, in other cases, the virus can cause a severe outbreak of shingles.
Painful rash along nerve pathways
The most common symptom of shingles is a painful rash that develops along the nerve pathways. The rash typically starts as a small cluster of red bumps or blisters on one side of the body. The rash can be extremely painful and may be accompanied by itching, tingling, or burning sensations.
The rash typically appears on the torso, back, or face. However, it can also occur on the arms, legs, or genitals. In some cases, the rash may spread to the eyes, ears, or mouth.
The pain associated with shingles can be severe and debilitating. It may be constant or intermittent, and it can last for weeks or even months. In some cases, the pain can be so severe that it interferes with sleep, work, and other daily activities.
In addition to the rash and pain, shingles can also cause other symptoms, such as fever, chills, fatigue, headache, and sensitivity to light. In some cases, shingles can also lead to complications, such as pneumonia, encephalitis, and meningitis.
If you are experiencing a painful rash, especially if it is accompanied by other symptoms such as fever, chills, or fatigue, it is important to see a doctor immediately. Early diagnosis and treatment of shingles can help reduce the risk of complications and shorten the duration of the illness.
Blisters and itching
One of the most common symptoms of shingles is a painful rash that is accompanied by blisters. The blisters typically start out as small, fluid-filled bumps. Over time, the blisters can grow larger and become filled with pus.
- Itching: The rash associated with shingles can be extremely itchy. In some cases, the itching can be so severe that it interferes with sleep and other daily activities.
- Blisters can break open: The blisters associated with shingles can break open, leaving open sores. These sores can be painful and may become infected.
- Risk of scarring: If the blisters are scratched or picked, they can become infected and lead to scarring.
- Secondary infection: The open sores caused by shingles can become infected with bacteria, leading to a secondary infection.
It is important to avoid scratching or picking the blisters associated with shingles. Scratching or picking can increase the risk of infection and scarring. If the itching is severe, a doctor may recommend using calamine lotion or other anti-itch medications.
Fever, chills, and fatigue
In addition to the rash and pain, shingles can also cause other symptoms, such as fever, chills, and fatigue.
Fever: Fever is a common symptom of shingles. The fever can be mild or severe, and it may last for several days.
Chills: Chills are another common symptom of shingles. Chills are often accompanied by fever, but they can also occur on their own.
Fatigue: Fatigue is a feeling of extreme tiredness or lack of energy. Fatigue is a common symptom of many illnesses, including shingles. The fatigue associated with shingles can be severe and may last for weeks or even months.
The fever, chills, and fatigue associated with shingles can make it difficult to perform everyday activities. In some cases, the symptoms may be so severe that they require hospitalization.
If you are experiencing fever, chills, and fatigue, especially if you also have a rash, it is important to see a doctor immediately. Early diagnosis and treatment of shingles can help reduce the risk of complications and shorten the duration of the illness.
Risk of complications
Shingles can lead to a number of complications, including:
- Postherpetic neuralgia (PHN): PHN is a chronic pain condition that can develop after shingles. PHN can cause severe pain, burning, and tingling sensations in the area where the shingles rash occurred. PHN can last for months or even years.
- Bacterial skin infection: The blisters associated with shingles can become infected with bacteria. Bacterial skin infections can be serious and may require treatment with antibiotics.
- Eye problems: Shingles can affect the eyes, leading to problems such as corneal ulcers, uveitis, and retinitis. These eye problems can lead to vision loss.
- Neurological complications: In rare cases, shingles can lead to neurological complications, such as encephalitis (inflammation of the brain) and meningitis (inflammation of the spinal cord and brain).
The risk of complications from shingles is highest in people over the age of 50 and those with weakened immune systems. People with diabetes, cancer, or HIV/AIDS are also at increased risk of complications from shingles.
Most common in older adults
Shingles is most common in people over the age of 50. The risk of shingles increases with age. This is because the immune system weakens with age, making people more susceptible to reactivation of the varicella-zoster virus.
- Age-related decline in immunity: As people age, their immune system weakens, making them more susceptible to reactivation of the VZV.
- Underlying health conditions: Older adults are more likely to have underlying health conditions, such as diabetes, heart disease, and cancer, which can weaken the immune system and increase the risk of shingles.
- Medications: Older adults are more likely to take medications that can suppress the immune system, such as corticosteroids and chemotherapy drugs. These medications can increase the risk of shingles.
- Stress: Stress can trigger reactivation of the VZV. Older adults may be more likely to experience stress due to retirement, bereavement, or other life changes.
It is important for older adults to be aware of the risk of shingles and to take steps to protect themselves, such as getting vaccinated against shingles and managing stress.
Vaccination available
There is a vaccine available to prevent shingles. The shingles vaccine is recommended for adults over the age of 50. The vaccine is also recommended for people with weakened immune systems, regardless of their age.
- Shingrix: Shingrix is a newer shingles vaccine that is more effective than the older Zostavax vaccine. Shingrix is a two-dose vaccine that is given 2 to 6 months apart.
- Zostavax: Zostavax is an older shingles vaccine that is still available. Zostavax is a single-dose vaccine that is given to people over the age of 60.
Both Shingrix and Zostavax are safe and effective vaccines. However, Shingrix is the preferred vaccine because it is more effective and provides longer-lasting protection against shingles.
Early diagnosis and treatment
Early diagnosis and treatment of shingles is important to reduce the risk of complications and shorten the duration of the illness. If you think you may have shingles, it is important to see a doctor right away.
The doctor will ask you about your symptoms and examine your rash. The doctor may also order blood tests or other tests to confirm the diagnosis.
Treatment for shingles typically includes antiviral medications, such as acyclovir, valacyclovir, and famciclovir. These medications can help to reduce the severity of the rash and pain. They can also help to prevent complications, such as PHN.
In addition to antiviral medications, your doctor may also recommend other treatments to relieve your symptoms. These treatments may include pain relievers, anti-itch medications, and cool compresses.
If you are diagnosed with shingles, it is important to follow your doctor's instructions carefully. Taking your medications as prescribed and following your doctor's other recommendations can help you to recover more quickly and reduce the risk of complications.
