Shingles: Symptoms, Causes, and Prevention

Shingles, also known as herpes zoster, is a painful skin rash caused by the reactivation of the varicella-zoster virus (VZV)—the same virus that causes chickenpox. While anyone who’s had chickenpox can develop shingles later in life, the risk increases with age, a weakened immune system, or certain chronic conditions.

Early diagnosis and treatment can reduce complications. Here’s what you need to know about shingles, including symptoms, causes, prevention, and when to contact a provider at BASS Medical Group.

What Are the Symptoms of Shingles?

Shingles symptoms often appear in three distinct stages:

1. Early Stage (Prodromal Phase)

Before a rash appears, you may experience:

  • Burning, tingling, or pain in a localized area.
  • Skin sensitivity.
  • Fatigue, headache, or a mild fever.

2. Rash Stage

  • A red rash appears on one side of the body or face.
  • The rash develops into fluid-filled blisters within a few days.
  • Discomfort, itching, or sharp nerve pain is common.

3. Healing & Recovery

  • Blisters scab over within 2–4 weeks.
  • Some individuals may develop postherpetic neuralgia (PHN)—long-term nerve pain that lingers after the rash heals.

What Causes Shingles?

After recovering from chickenpox, the virus remains dormant in your nervous system. Shingles occurs when that virus reactivates, often years or decades later. Common risk factors include:

  • Age 50+
  • Weakened immune system (e.g., cancer, HIV, autoimmune conditions)
  • High stress levels
  • Certain medications that suppress immunity

How to Prevent Shingles

1. Get Vaccinated

The Shingrix vaccine is the most effective way to prevent shingles and its complications. It’s recommended for:

  • Adults age 50 and older
  • Adults 19+ with weakened immune systems

Shingrix is given in two doses and is over 90% effective.

2. Support Your Immune System

  • Eat a healthy, balanced diet
  • Stay active with regular exercise
  • Reduce stress through mindfulness, sleep, and relaxation techniques

3. Avoid Spreading the Virus

If you have shingles:

  • Keep the rash clean and covered
  • Avoid contact with people who haven’t had chickenpox or the chickenpox vaccine

How Is Shingles Treated?

Early treatment is key to reducing complications, especially postherpetic neuralgia.

1. Antiviral Medications

Drugs like acyclovir, valacyclovir, and famciclovir can shorten the illness if started within 72 hours of symptom onset.

2. Pain Relief

  • Over-the-counter pain relievers like acetaminophen or ibuprofen
  • Prescription pain meds or nerve treatments for chronic pain

3. Comfort Measures

  • Cool compresses or oatmeal baths to soothe the rash
  • Calamine lotion to relieve itching

When to See a Doctor

Contact a healthcare provider if:

  • You are over age 60
  • The rash is near your eyes or spreads across the body
  • You have a weakened immune system
  • You develop long-term nerve pain
