Shingles, also known as herpes zoster, is a painful viral skin infection caused by reactivation of the varicella-zoster virus (VZV)—the same virus responsible for chickenpox. After a person recovers from chickenpox, the virus remains dormant in the nervous system and may reactivate years later, causing a painful blistering rash. Early diagnosis and prompt treatment are important because antiviral medications are generally most effective when started within 72 hours of rash onset and may help reduce complications, including postherpetic neuralgia. At BOME Dermatology Clinic in Apgujeong, Gangnam, a board-certified dermatologist (M.D., Ph.D.) provides comprehensive diagnosis and personalized treatment for shingles using evidence-based dermatology. Every patient receives an individualized evaluation focused on confirming the diagnosis, relieving symptoms, promoting skin healing, and minimizing the risk of long-term nerve pain.

Whether you have newly developed shingles, facial shingles, recurrent blistering rashes, or lingering pain after the rash has healed, BOME offers physician-led dermatologic care for Korean residents, expatriates, and international patients.

What Is Shingles?

Shingles occurs when the varicella-zoster virus reactivates after remaining inactive within sensory nerves for many years following childhood chickenpox.

Unlike chickenpox, shingles usually affects only one nerve distribution (dermatome), causing:

• Pain
• Burning
• Tingling
• Clusters of fluid-filled blisters
• Localized skin sensitivity

The rash almost always appears on one side of the body or face and rarely crosses the body's midline.

Common Symptoms

Early symptoms may begin several days before the rash appears.

Patients commonly experience:

• Burning pain
• Tingling sensation
• Skin sensitivity
• Itching
• Sharp nerve pain
• Red rash
• Fluid-filled blisters
• Crusting during healing
• Fatigue
• Mild fever

Pain may be severe even before blisters become visible.

Who Is at Higher Risk?

Several factors increase the risk of developing shingles:

Older Age

The risk increases significantly after age 50.

Previous Chickenpox

Anyone who has had chickenpox carries the dormant virus.

Reduced Immune Function

Illness, certain medications, or immune suppression may increase the likelihood of viral reactivation.

Stress

Significant emotional or physical stress may contribute to outbreaks.

Chronic Medical Conditions

Conditions affecting immune function may increase susceptibility.

Types of Shingles

Truncal Shingles

The most common form, affecting the chest, abdomen, or back.

Facial Shingles

Occurs when the trigeminal nerve is involved and may affect the forehead, nose, or cheek.

Ophthalmic Shingles

When shingles affects the eye or surrounding structures, urgent medical evaluation is recommended because vision-threatening complications can occur.

Disseminated Shingles

A rare but more extensive form seen primarily in immunocompromised individuals.

Conditions That May Resemble Shingles

A board-certified dermatologist carefully distinguishes shingles from:

• Herpes simplex infection
• Contact dermatitis
• Allergic skin reactions
• Insect bites
• Bacterial skin infections
• Bullous skin diseases
• Cellulitis
• Fungal skin infections

Accurate diagnosis helps ensure timely antiviral treatment while avoiding unnecessary medications.

Comprehensive Dermatologic Evaluation

During your consultation, your dermatologist evaluates:

• Symptom onset
• Pain severity
• Rash distribution
• Blister appearance
• Medical history
• Immune status
• Current medications
• Previous shingles episodes
• Chickenpox history
• Risk factors

When clinically appropriate, additional investigations may include:

• Viral PCR testing
• Viral swab testing
• Laboratory evaluation
• Skin biopsy in atypical cases

Testing is generally reserved for uncertain or unusual presentations.

Personalized Shingles Treatment

Treatment depends on the stage of infection, symptom severity, age, and overall health.

Oral Antiviral Medication

Prescription antiviral medications may shorten the duration of illness and reduce complications when started as early as possible after symptom onset.

Pain Management

Your dermatologist develops an individualized plan to help manage nerve pain during the active infection and recovery period.

Skin Care During Healing

Patients receive guidance regarding:

• Gentle cleansing
• Blister care
• Skin protection
• Prevention of secondary bacterial infection
• Scar minimization

Management of Postherpetic Neuralgia

Some patients continue to experience nerve pain after the rash heals. Persistent symptoms may require ongoing evaluation and individualized management.

Prevention Education

Patients receive counseling regarding:

• Vaccination discussions with their primary healthcare provider when appropriate
• Household precautions
• Skin care
• When urgent medical attention is necessary

What to Expect During Your Visit

Step 1 – Consultation

Your dermatologist reviews your symptoms, medical history, medications, and timing of rash onset.

Step 2 – Skin Examination

A detailed examination evaluates the distribution, severity, and stage of the rash.

Step 3 – Diagnosis

The dermatologist confirms whether the rash is shingles or another skin condition requiring different treatment.

Step 4 – Personalized Treatment Plan

Recommendations may include:

• Oral antiviral medication
• Pain management
• Wound care instructions
• Follow-up monitoring
• Referral for urgent ophthalmologic evaluation if eye involvement is suspected

Step 5 – Follow-Up

Patients with facial involvement, severe pain, or persistent nerve symptoms receive ongoing monitoring to optimize recovery.

Why Early Treatment Matters

Prompt medical evaluation is important because early treatment may:

• Shorten the duration of symptoms
• Reduce viral activity
• Improve skin healing
• Lower the risk of postherpetic neuralgia
• Reduce secondary bacterial infection
• Minimize long-term complications

Patients who develop a painful rash on one side of the body should seek medical assessment as soon as possible.

When Should You Seek Urgent Medical Care?

Immediate medical evaluation is recommended if:

• The rash involves the eyes
• Vision changes occur
• Severe facial pain develops
• The rash spreads extensively
• High fever accompanies the rash
• You have a weakened immune system
• Severe neurological symptoms occur

Why Choose a Board-Certified Dermatologist?

Shingles can resemble several inflammatory and infectious skin diseases, making self-diagnosis unreliable. A board-certified dermatologist has specialized expertise in recognizing herpes zoster, determining when antiviral treatment should begin, identifying high-risk presentations such as ophthalmic shingles, and monitoring patients for complications such as postherpetic neuralgia. At BOME, every treatment recommendation is based on accurate diagnosis, evidence-based dermatology, and individualized patient care.

Frequently Asked Questions

What causes shingles?

Shingles occurs when the varicella-zoster virus, which remains dormant after chickenpox, becomes active again later in life.

Is shingles contagious?

A person with shingles cannot transmit shingles itself, but the virus can spread to someone who has never had chickenpox or the chickenpox vaccine, potentially causing chickenpox rather than shingles.

When should antiviral medication be started?

Antiviral medications are generally most effective when started within 72 hours of the appearance of the rash. Early medical evaluation is recommended.

Can shingles cause permanent pain?

Some patients develop postherpetic neuralgia, a condition in which nerve pain persists after the skin has healed. Early diagnosis and treatment may reduce the risk, although it cannot always be prevented.

Do you treat international patients?

Yes. BOME Dermatology Clinic provides English-friendly consultations and personalized treatment plans for international patients with shingles, herpes simplex, viral skin infections, bacterial skin infections, fungal skin infections, and other medical dermatologic conditions.
