What Is Shingles and Why Does It Occur?
Shingles, medically known as herpes zoster, is a viral infection that causes a painful skin rash and nerve-related symptoms. It develops when the varicella-zoster virus—the same virus responsible for chickenpox—becomes active again after remaining dormant in the body’s nerve tissue for many years.
Across Australia, shingles is a common health condition. Research suggests that approximately one in three Australians will experience shingles at some point during their lifetime, with the likelihood increasing significantly after the age of 50.
Unlike chickenpox, shingles is not typically spread through the air. Instead, the dormant virus reactivates within nerve pathways and travels to the skin, producing a distinctive rash that generally affects only one side of the body or face.
Current Australian estimates indicate that more than 120,000 people are diagnosed with shingles every year. One of the most significant complications is post-herpetic neuralgia (PHN), a persistent form of nerve pain that can continue long after the visible rash has disappeared. Studies show that between 5% and 30% of people who develop shingles may experience PHN, with older Australians facing the greatest risk.
At First Aid Pro Sydney, we believe that understanding common medical conditions helps people respond more confidently during health-related situations. Our nationally recognised first aid courses provide practical knowledge that supports informed decision-making during a wide range of medical emergencies.
Essential Facts About Shingles
- Shingles is caused by the reactivation of the varicella-zoster virus.
- Around one in three Australians will develop shingles during their lifetime.
- Early medical treatment can reduce symptom severity and complication risks.
- Vaccination remains the most effective form of prevention.
- Post-herpetic neuralgia can cause long-lasting nerve pain.
- Medical assessment within 72 hours of rash development provides the best opportunity for effective treatment.
Early Signs of Shingles: Recognising the Warning Signals
The virus responsible for shingles can remain inactive for decades before becoming active again. Identifying the earliest symptoms can help improve recovery outcomes and reduce the risk of complications.
How a Shingles Outbreak Typically Begins
Following a previous chickenpox infection, the varicella-zoster virus remains hidden within nerve tissue. Certain triggers may allow the virus to reactivate, including:
- Advancing age
- Physical or emotional stress
- Reduced immune function
- Certain medical conditions
- Some medications
When the virus reactivates, symptoms often develop gradually before the rash becomes visible.
Common Symptoms Associated With Shingles
The most frequently reported symptoms include nerve pain, skin sensitivity, rash, blisters, itching, and general illness symptoms.
Nerve Pain
Pain is often the first sign of shingles and may feel burning, stabbing, tingling, or sharp. In some cases, pain begins several days before any rash appears.
Increased Skin Sensitivity
The affected area may become unusually sensitive to touch, clothing, temperature changes, or pressure.
Distinctive Skin Rash
A red rash usually develops on one side of the body or face, following the path of a specific nerve.
Fluid-Filled Blisters
Clusters of blisters often appear shortly after the rash develops. These blisters may burst before forming scabs during healing.
Itching and Discomfort
Many people experience moderate to severe itching alongside pain and skin irritation.
General Illness Symptoms
Some individuals also report:
- Headaches
- Fatigue
- Fever
- General feelings of being unwell
Why Shingles Usually Appears on One Side
Because shingles follows nerve pathways known as dermatomes, the rash generally remains confined to one side of the body and rarely crosses the body's midline.
Understanding the Stages of Shingles
Most cases of shingles follow a predictable progression.
Stage | Typical Duration | Common Symptoms | What’s Happening |
Early Stage | 1–5 days | Tingling, burning, pain, headache, fatigue | Virus becomes active and travels through nerves |
Rash Development | 2–3 days | Red patches appear | Virus reaches the skin |
Blister Stage | 3–5 days | Fluid-filled blisters form | Active viral activity |
Healing Phase | 7–10 days | Blisters crust and heal | Viral activity declines |
Recovery Period | Variable | Possible ongoing nerve pain | Nerve irritation or damage may persist |
Important Warning Sign
Many people experience severe pain several days before a rash develops. This early pain can sometimes be mistaken for:
Heart-Related Problems
Kidney Conditions
Musculoskeletal Injuries
Spinal Issues
Seek Medical Advice Promptly
If you develop unexplained pain, tingling, or burning sensations on one side of your body, particularly if you are over 50 years of age, seek medical advice promptly.
How Doctors Diagnose Shingles
In most cases, Australian GPs can diagnose shingles through a physical examination and discussion of symptoms.
The characteristic rash pattern combined with nerve pain is often enough to confirm the diagnosis.
Where symptoms are less typical, further testing may include:
- Laboratory analysis of blister fluid
- Polymerase chain reaction (PCR) testing
- Blood tests to assess immune function
Why Early Diagnosis Matters
Antiviral medications provide the greatest benefit when started within 72 hours of the rash appearing. Prompt assessment can shorten illness duration and reduce the likelihood of complications.
Can Shingles Occur After Having Chickenpox?
Yes. Anyone who has previously had chickenpox carries the varicella-zoster virus within their body. Although the infection resolves, the virus remains dormant in nerve tissue and may reactivate years later as shingles.
Who Is Most at Risk?
Shingles can affect:
- Anyone who has previously had chickenpox
- People who received the chickenpox vaccine (although risk is lower)
- Adults over 50 years of age
- Individuals with weakened immune systems
- People experiencing significant physical or emotional stress
Is Shingles Contagious?
You cannot directly catch shingles from another person.
However, someone with active shingles can pass the varicella-zoster virus to a person who has never had chickenpox or has not received the chickenpox vaccine. In those cases, the exposed individual may develop chickenpox rather than shingles.
Shingles Vaccination in Australia
Vaccination is currently the most effective method of preventing shingles and reducing the risk of serious complications.
Who Should Consider Vaccination?
The recombinant zoster vaccine (Shingrix) is the preferred shingles vaccine used throughout Australia.
Group | Eligibility | Cost | Effectiveness |
Adults aged 65 years and over | Eligible under NIP | Free for eligible groups | Up to 97% effective |
Aboriginal and Torres Strait Islander people aged 50+ | Eligible under NIP | Free | Approximately 90–97% effective |
Immunocompromised adults aged 18+ | Eligible under NIP | Free | Strong protection depending on condition |
How to Access the Vaccine
You can discuss vaccination with:
- Your GP
- Participating community pharmacies
- Vaccination clinics
Even people who have previously experienced shingles may still benefit from vaccination to reduce the risk of future episodes.
Potential Complications Associated With Shingles
While many people recover without major issues, shingles can occasionally lead to serious complications.
Post-Herpetic Neuralgia (PHN)
PHN is the most common complication and involves ongoing nerve pain that continues after the rash has healed. For some people, symptoms may persist for months or even years.
Eye Involvement
When shingles affects the eye or surrounding facial nerves, vision problems and permanent eye damage can occur.
Neurological Complications
Rare complications may include:
- Facial paralysis
- Hearing loss
- Brain inflammation, also known as encephalitis
Secondary Skin Infections
Scratching or poor wound care can allow bacteria to infect the affected skin.
Widespread Shingles
People with significantly weakened immune systems may develop more extensive outbreaks affecting multiple areas of the body.
Managing Shingles Day to Day
Although antiviral medication is often required, several self-care measures can improve comfort and support recovery.
Stay Ahead of Pain
Taking pain relief medication as directed may help maintain more consistent symptom control and improve day-to-day comfort.
Protect the Skin
Keep the affected area clean and avoid irritating creams, lotions, or products unless advised by a healthcare professional.
Use Cool Compresses
Applying a cool, damp cloth may help reduce discomfort, itching, and inflammation associated with the rash.
Wear Comfortable Clothing
Loose-fitting cotton clothing can minimise friction and irritation on sensitive or painful skin.
Reduce Stress Levels
Gentle exercise, relaxation techniques, mindfulness, and adequate sleep may support recovery and overall wellbeing.
Prioritise Rest
Allowing your body additional recovery time can assist immune function and support the healing process.
First Aid Considerations for Shingles
Although shingles requires medical assessment, several simple first aid measures can help reduce discomfort and minimise the risk of complications.
