Shingles is a viral skin disease that causes painful rashes, usually appearing as a stripe on one side of the body. It is caused by the varicella-zoster virus — the same virus that causes chickenpox.
After a person recovers from chickenpox, the virus remains in the body in a “dormant” state. Years later, it can reactivate and cause shingles.
The condition is not rare and is more common in adults. It is not as easily transmitted as chickenpox, but contact with active blisters can infect someone who has never had chickenpox before.
What to do if suspected
If you feel burning, tingling, or pain in an area of skin followed by blisters, it is important not to delay seeking medical help. The first step is to see a doctor (general practitioner, dermatologist, or infectious disease specialist). Early treatment helps reduce symptom severity and lowers the risk of complications. Before seeing a doctor, do not open or scratch the blisters or apply heat to the affected area. This may worsen inflammation and slow healing. Do not ignore symptoms, especially if the pain is strong or increasing. Timely treatment significantly improves the course of the disease.
What the condition looks like
At first, redness and pain appear in a limited area of skin. Within 1–3 days, clusters of fluid-filled blisters develop. The rash usually appears in a band-like pattern along a nerve path and typically affects only one side of the body — for example, the chest, abdomen, back, or face. Over time, the blisters burst, dry out, and form crusts. Below in the article you may view real photos to better understand how the condition looks.
Main symptoms
Symptoms may develop gradually and include both skin and nerve-related signs. Common symptoms: burning, tingling, or skin pain; increased sensitivity in the affected area; blister formation; mild fever; fatigue. In some cases, pain may persist after the rash disappears. This is called postherpetic neuralgia.
Causes
The main cause is reactivation of the varicella-zoster virus. After chickenpox, the virus remains in nerve cells. When the immune system weakens, it can “wake up” and cause inflammation of nerves and skin.
How it develops
When the virus reactivates, it travels along nerve fibers to the skin. This causes inflammation, pain, and a characteristic rash. The affected area is usually limited to a single region supplied by one nerve. The immune system gradually suppresses the virus, and the lesions heal, but recovery may take time.
Forms and types
The most common form is the typical unilateral rash. In some cases, more severe forms occur — for example, when the face or eyes are affected, requiring urgent medical attention.
When to see a doctor
Seek medical attention if there is significant skin pain, characteristic blisters appear, the face or eyes are affected, symptoms rapidly worsen, or the person has chronic illness or weakened immunity. Early treatment reduces the risk of complications.
Treatment
Treatment focuses on suppressing the virus and relieving symptoms. Antiviral medications are the main therapy and are most effective when started in the first days of illness. Pain relievers and skin care treatments may also be used to reduce irritation and promote healing. In more severe cases, closer medical supervision may be required.
Q&A
Can shingles be completely cured?
Yes, the rash heals, but the virus remains in the body and can reactivate again.
Is shingles contagious?
It is less contagious than chickenpox, but the virus can spread through contact with active lesions.
Why is the pain so strong?
The virus affects nerve fibers, leading to significant nerve pain.
How long does it last?
Usually, the rash heals within 2–4 weeks.
Can pain remain after recovery?
Yes, postherpetic neuralgia may occur, where pain persists after healing.
Can I shower during shingles?
Yes, hygiene is important, but avoid rubbing or irritating the skin.
Who gets shingles more often?
It is more common in older adults or people with weakened immunity.
Can shingles be prevented?
Risk can be reduced with good health maintenance and vaccination when recommended.
