Shingles Pain: Why It Happens and How It Can Be Treated

Shingles pain can be intense, persistent, and difficult to manage. While many people recognise the characteristic rash, the pain associated with shingles can be severe and long-lasting, sometimes continuing even after the skin has healed.

Understanding why shingles causes pain — and how it can be treated — is key to improving recovery and quality of life.

What is Shingles?

Shingles (herpes zoster) is caused by reactivation of the varicella-zoster virus, the same virus that causes chickenpox. After the initial infection, the virus lies dormant in the nervous system and can reactivate later in life.

When it reactivates, it travels along a nerve, causing:

• A painful rash, typically on one side of the body
• Nerve inflammation and irritation
• Ongoing pain that may persist beyond the rash

Why Does Shingles Cause Pain?

Shingles directly affects the nerves, making it a form of neuropathic pain.

The virus causes:

• Inflammation and damage to nerve fibres
• Abnormal pain signalling to the brain
• Heightened sensitivity in the affected area

This is why shingles pain is often described as burning, stabbing, or electric shock-like, and may be triggered by even light touch.

What is Post-Herpetic Neuralgia (PHN)?

In some people, pain continues after the rash has healed — a condition known as post-herpetic neuralgia (PHN).

PHN can:

• Persist for months or even years
• Cause constant burning or aching pain
• Lead to hypersensitivity (pain from clothing or light touch)
• Affect sleep, mood, and daily function

The risk of PHN increases with age and severity of the initial infection.

Common Symptoms of Shingles Pain

Shingles-related pain may include:

• Burning or throbbing discomfort
• Sharp, shooting sensations
• Tingling or numbness
• Sensitivity to touch or temperature
• Persistent pain after the rash resolves

Why Shingles Pain Can Become Chronic

Pain may persist when:

• Nerve damage is significant
• The nervous system becomes sensitised, amplifying pain signals
• Healing of the nerve is incomplete
• Pain pathways remain “overactive”

This transition from acute to chronic pain is why early and effective treatment is important.

Treatment Options

Management depends on the stage and severity of symptoms.

Early Treatment

• Antiviral medications (to reduce viral activity)
• Pain relief medications
• Anti-inflammatory strategies

For Persistent or Chronic Pain

When pain continues, more targeted treatments may be required.

• Medications for neuropathic pain
• Topical treatments
• Interventional pain procedures

Advanced Treatment Options

At Anodyne, we focus on treating treatment resistant pain conditions, when the underlying nerve dysfunction persists despite adequate treatment.

Ketamine therapy can help:

• Reduce abnormal nerve signalling
• Decrease central sensitisation
• Improve pain control in post-herpetic neuralgia
• Support recovery when standard treatments have failed

In selected cases, Stellate Ganglion Block (SGB), particularly when symptoms involve the head, neck, or upper limb, may:

• Reduce nerve inflammation
• Improve blood flow
• Calm overactive sympathetic responses contributing to pain

The Importance of Early Intervention

Treating shingles pain early can reduce the risk of long-term complications such as PHN. Prompt assessment and targeted therapy can:

• Limit nerve damage
• Reduce pain severity
• Improve recovery outcomes

Living with Shingles Pain

Shingles pain can be physically and emotionally exhausting. Sleep disruption, anxiety, and reduced activity are common — especially when pain persists.

A comprehensive approach that includes:

• Medical treatment
• Pain modulation
• Ongoing monitoring

is key to achieving meaningful improvement.

Final Thoughts

Shingles pain is more than a skin condition — it is a nerve disorder that can persist long after the rash disappears.

With the right treatment approach, including advanced therapies where needed, many patients can achieve significant relief and improved quality of life.
