Shingles (herpes zoster) is a painful viral infection caused by the reactivation of the varicella-zoster virus, the same virus that causes chickenpox. After a person recovers from chickenpox, the virus remains dormant in nerve tissues and can re-emerge years later as shingles. This condition affects 1 in 3 adults in their lifetime, particularly those over 50 or with weakened immune systems.
In this article, we’ll cover:
✔ Shingles symptoms (including the telltale rash)
✔ Shingles treatment options (medications & home remedies)
✔ Is shingles contagious? (transmission risks)
✔ Postherpetic neuralgia (chronic pain complication)
✔ Shingles vaccine (prevention & effectiveness)
Shingles Symptoms: Early Signs to Watch For
Shingles typically progresses in stages:
Early Symptoms (Before Rash Appears)
• Tingling, burning, or itching on one side of the body (often the torso, face, or neck)
• Sensitivity to touch
• Flu-like symptoms (fatigue, fever, headache)
Active Shingles Rash
• A painful, red rash that develops into fluid-filled blisters
• Usually appears in a single stripe on one side of the body
• Blisters scab over in 7–10 days and heal within 2–4 weeks
Complications
• Postherpetic neuralgia (PHN) – Persistent nerve pain lasting months or years after the rash heals (affects 10–18% of patients)
• Vision loss (if shingles affects the eye)
• Skin infections (from scratching blisters)
Shingles Treatment: How to Manage the Virus
Early treatment (within 72 hours of rash onset) can reduce severity and complications.
Medical Treatments
• Antiviral medications (Acyclovir, Valacyclovir, Famciclovir) – Speed healing and lower pain risk
• Pain relievers (NSAIDs, gabapentin, or prescription opioids for severe pain)
• Topical creams (Calamine lotion, capsaicin cream) – Soothe itching
Home Remedies
• Cool compresses – Reduce inflammation
• Oatmeal baths – Relieve itching
• Loose clothing – Prevent irritation
Dr. Jen Haley, a board-certified dermatologist, emphasizes: "Starting antivirals early is key to minimizing nerve damage and PHN risk."
Is Shingles Contagious?
Shingles itself isn’t contagious, but the virus can spread to people who haven’t had chickenpox or the vaccine, causing chickenpox—not shingles. To prevent transmission:
• Cover the rash
• Avoid touching blisters
• Shingles treatment Stay away from high-risk individuals (pregnant women, infants, immunocompromised people)
Postherpetic Neuralgia (PHN): Chronic Pain After Shingles
PHN is the most common complication, causing long-term burning, stabbing, or electric-shock-like pain. Treatments include:
• Nerve pain medications (Lyrica, gabapentin)
• Lidocaine patches
• Steroid injections
Shingles Vaccine: Best Prevention
The Shingrix vaccine (recommended for adults 50+) is 90% effective at preventing shingles and PHN. Key facts:
• Given in 2 doses, 2–6 months apart
• Safe for those who’ve had shingles before
• Covered by most insurance plans
Final Thoughts
Shingles can be extremely painful, but early antiviral treatment and vaccination significantly reduce risks. If you suspect shingles, see a doctor immediately to start therapy. For those eligible, Shingrix is the best defense against this debilitating virus.
