Shingles (Herpes Zoster) Explained

Shingles (Herpes Zoster) Explained

Health Issue Classification:

• Infection

Cause:

• Reactivation of the varicella-zoster virus (the virus that causes chickenpox) after lying dormant in nerve tissue for years. Often triggered by stress, ageing, or weakened immunity.

Symptoms

• Painful rash with fluid-filled blisters (usually on one side of the body or face)
• Tingling or burning sensation before the rash appears
• Itching or sensitivity in the affected area
• Fatigue, fever, or headache
• Nerve pain (postherpetic neuralgia) that can last for months after the rash resolves

Management

• Antiviral medications (e.g., acyclovir, valacyclovir) to reduce severity and duration
• Pain relief with NSAIDs or prescription pain medications
• Cold compresses and calamine lotion to soothe itching
• Rest and stress management to support healing
• Vaccination (Shingrix) to prevent future outbreaks

Exams & Tests

• Clinical Examination: Diagnosis is based on the appearance of the rash and symptoms.
• Tzanck Test: A skin biopsy or scraping may be taken to confirm the presence of the virus.
• PCR Test: A polymerase chain reaction test to detect varicella-zoster virus DNA in blister fluid.

Blood Test Biomarkers

• None specific for Shingles
  • Blood tests may help confirm varicella-zoster infection in certain cases or rule out other infections that mimic shingles.

Health Professionals

• Dermatologist
• Infectious Disease Specialist
• Primary Care Physician
• Neurologist (for postherpetic neuralgia)

Health Vital Devices & Monitors

• Skin care products (e.g., calamine lotion) for rash relief
• Pain-relief devices such as TENS (for postherpetic neuralgia)
• Wearables to monitor fever and sleep patterns during recovery

Possible Treatments

Antiviral Medications:

• Acyclovir, Valacyclovir, or Famciclovir to reduce viral replication and speed recovery (most effective if started within 72 hours of symptom onset).

Pain Management:

• NSAIDs (e.g., ibuprofen) or prescription pain medications for relief
• Topical lidocaine or capsaicin cream for localized pain
• Antidepressants or anticonvulsants (e.g., gabapentin) for postherpetic neuralgia

Preventive Measures:

• Shingles Vaccine (Shingrix): Recommended for adults over 50 and those with weakened immune systems to prevent shingles or reduce its severity.

Nutrition Dos

• Stay hydrated to support immune function and healing
• Eat foods rich in vitamins C and E (e.g., citrus fruits, nuts) to promote skin healing
• Include immune-boosting foods (e.g., leafy greens, garlic, turmeric)
• Consume foods rich in lysine (e.g., yogurt, fish) to help reduce viral activity
• Consider vitamin supplements (e.g., vitamin D) if recommended by your doctor

Nutrition Don’ts

• Avoid high-arginine foods (e.g., chocolate, nuts) that may trigger virus activity
• Limit sugar and processed foods that can weaken the immune system
• Reduce alcohol consumption, as it can interfere with healing
• Avoid caffeine if it exacerbates pain or stress

Lifestyle Dos

• Keep the rash clean and covered to avoid infection or spreading the virus
• Get plenty of rest to help the body heal
• Use cold compresses or oatmeal baths to relieve itching
• Manage stress through relaxation techniques (e.g., meditation, deep breathing)
• Maintain a healthy diet to support the immune system
• Avoid close contact with people who have not had chickenpox or the chickenpox vaccine (especially pregnant women and immunocompromised individuals)

Lifestyle Don’ts

• Don’t scratch the rash, as it can lead to infection
• Avoid sharing towels, clothing, or bedding with others
• Don’t delay starting antiviral medications (most effective if taken early)
• Avoid vigorous exercise or stress, as they can worsen symptoms
• Don’t ignore symptoms of postherpetic neuralgia (prolonged nerve pain after the rash heals)

Emergency Situations: Severe Pain or Complications

• Severe Pain or Rash Near the Eyes:
  • Action: If the rash affects the eyes or face, or if you experience severe pain, vision changes, or hearing loss, seek immediate medical attention to avoid complications like permanent nerve or eye damage.
• Postherpetic Neuralgia:
  • Action: If severe nerve pain persists after the rash resolves, consult a doctor or neurologist for long-term pain management options.
