Clinical Overview
Post-herpetic neuralgia (PHN) is a lasting pain in the areas of your skin where you had shingles (herpes zoster). It occurs if nerve fibers are damaged during an outbreak of shingles. In Ayurveda, this condition represents a severe 'Pittavruta Vata' pathology—where the burning, inflammatory nature of Pitta damages the nerves, leaving behind a highly sensitive, painful state dominated by Vata dosha.
Emergency Warning Signs
Seek immediate conventional medical care if you experience any of the following:
- Signs of a secondary bacterial infection at the rash site (pus, increased redness)
- Severe headache, stiff neck, or changes in consciousness
- Vision changes if the original shingles rash was on your face
Symptomatology
Burning And Stabbing Pain
Clinical manifestation characterized by burning and stabbing pain. Ayurvedic assessment involves evaluating the specific Dosha and Srotas involvement underlying this symptom.
Extreme Sensitivity To Touch
Clinical manifestation characterized by extreme sensitivity to touch. Ayurvedic assessment involves evaluating the specific Dosha and Srotas involvement underlying this symptom.
Itching And Numbness
Clinical manifestation characterized by itching and numbness. Ayurvedic assessment involves evaluating the specific Dosha and Srotas involvement underlying this symptom.
Muscle Weakness Rare
Clinical manifestation characterized by muscle weakness rare. Ayurvedic assessment involves evaluating the specific Dosha and Srotas involvement underlying this symptom.
Temperature Sensitivity
Clinical manifestation characterized by temperature sensitivity. Ayurvedic assessment involves evaluating the specific Dosha and Srotas involvement underlying this symptom.
Diagnostic Protocol
Ayurvedic Assessment
Nadi Pariksha indicates 'Pitta-Vata' dual aggravation. The Rakta (blood) and Majja (nervous tissue) show signs of intense depletion and 'Daha' (burning). The focus is assessing how deeply the Pitta 'heat' has scorched the Vata pathways.

Classical Perspective
Samprapti (Pathogenesis)
The Herpes Zoster virus acts as an intense 'Visarpa' (erysipelas-like) or 'Kaksha' pathology characterized by severe Pitta and Rakta vitiation. When the acute rash resolves, the residual heat has 'dried up' the local snigdha (unctuous) qualities of the nerves (Majja). This leaves the nerve pathways exposed and hypersensitive, causing Vata to become severely aggravated, leading to chronic neuralgic pain.

Frequently Asked Questions
Why does my skin hurt even when my clothes touch it?
This is a symptom called allodynia, common in PHN. The shingles virus damaged your nerve fibers, making them highly excitable. In Ayurveda, this means Vata is hyperactive because its protective covering has been 'burnt' by Pitta. We use cooling, unctuous therapies to repair this covering.
Can Ayurvedic treatment be taken along with Gabapentin or Pregabalin?
Yes. Ayurvedic treatments are highly complementary. Our localized therapies (like Dhara and Lepam) work physically on the damaged nerves, while herbal medicines work on reducing inflammation. Many patients find they can gradually reduce their conventional dosage under medical supervision.
