Shingles (Herpes Zoster) is caused by reactivation of the varicella-zoster virus — the same virus responsible for chickenpox. While the rash and blisters eventually heal, some people experience persistent nerve pain in the affected area for weeks, months, or even years. This condition is known as Post-Herpetic Neuralgia (PHN) and is one of the most common complications of shingles.
Why Does PHN Happen?
After shingles, the virus can cause lasting nerve damage in the affected skin area. This damaged nerve continues to send abnormal pain signals to the brain, even after the rash has healed.
Symptoms
- Burning, stabbing, or electric shock–like pain in the same area as the shingles rash
- Pain that worsens with touch (even clothes brushing against the skin)
- Sensitivity to temperature changes
- Itching or numbness
Risk Factors
- Age over 50 years
- Severe initial shingles rash
- Presence of intense pain during the acute shingles phase
- Immunocompromised state
Treatment Options
At ALGOS Pain Clinic, our approach to PHN is multi-modal:
- Medications: Nerve pain medicines (Gabapentin, Pregabalin), certain antidepressants, topical agents like Lidocaine patches
- Nerve Blocks: Targeted injections to calm irritated nerves and reduce pain
- Neuromodulation: Techniques like pulsed radiofrequency or spinal cord stimulation for severe, persistent cases
- Ozone Therapy: In some cases, ozone therapy can reduce inflammation and promote healing of damaged nerves
Can PHN Be Prevented?
The best prevention is early treatment of shingles with antiviral medication and adequate pain control. Vaccination against shingles (Herpes Zoster vaccine) is highly recommended for older adults.
Final Word
PHN can significantly affect quality of life, but with the right pain management strategies, patients can experience lasting relief. If you or someone you know is struggling with nerve pain after shingles, our specialists at ALGOS Pain Clinic are here to help.
