Post-Herpetic Neuralgia Treatment in Singapore – FAQs

What is post-herpetic neuralgia (PHN)?

PHN is long-term nerve pain that occurs after a shingles (herpes zoster) outbreak. Even after the rash resolves, nerve damage can lead to persistent burning, stabbing, or electric-like pain.

What causes PHN?

PHN results from damage to sensory nerves during a shingles infection. These nerves may continue to misfire, causing pain that lasts months or even years after the rash heals.

What are common symptoms?

• Burning or sharp nerve pain in the affected area

• Sensitivity to light touch (even from clothing)

• Tingling, numbness, or skin irritation

• Pain worsened by temperature or stress

• Sleep and mood disturbances

How long does PHN last?

Some patients recover within 3–6 months, but others may have symptoms for a year or more. Early intervention improves outcomes.

What are typical treatments for PHN?

Doctors often prescribe:

• Antivirals (during shingles phase)

• Painkillers, antidepressants, or anti-epileptic medications

• Topical creams or lidocaine patches

• Nerve blocks

What are the limitations of conventional treatments?

• Pain relief may be temporary or incomplete

• Side effects from long-term medications

• Some patients experience medication resistance

• Nerve blocks may wear off or require repetition

How does The Pain Relief Practice manage PHN differently?

We focus on non-invasive nerve repair therapies that reduce sensitivity and inflammation:

• Shockwave therapy to improve microcirculation and stimulate tissue healing

• HotHeal Therapy Protocol — pioneered by our clinic — using manual therapy and non-invasive radiofrequency for pain modulation

• Pioneered Home Therapy Protocol, which combines:

  • FDA-approved PEMF therapy (backed by Oxford Journal studies)

  • Regenerix Gold — a premium supplement supporting nerve and joint repair

  • Korean transdermal technology for deep skin-layer delivery

These options are ideal for patients who want to avoid long-term medication use or are seeking alternatives after limited results elsewhere.

Are these treatments painful or invasive?

No. They are non-invasive and well-tolerated, even for patients with extreme skin sensitivity.

When is surgery needed?

Surgery is rarely recommended for PHN. However, we provide second opinions for patients considering invasive procedures or who have persistent unresolved pain.
