Post-herpetic neuralgia (PHN) is a neuropathic pain syndrome. It is characterized by persistent pain (for months to years) after the resolution of the herpes zoster (HZ) rash. Herpes zoster is a clinical condition caused by the varicella-zoster virus. It is a primary chickenpox infection, which remains latent in the body for decades. Reactivation of this varicella virus without rashes can produce neuralgia. The varicella-zoster virus affects the skin, especially the sides of the chest. After a herpes episode, the virus remains silent and dormant in the body’s nerve cells. This virus may become active when the individual’s immunity reduces or during recovery after a significant illness, resulting in blisters on the skin. It is accompanied by a rash that disappears in about two to four weeks without substantial consequences.

Role of homeopathy in post-herpetic neuralgia

Post-herpetic neuralgia occurs when there is persistent and recurrent pain in the area of the body affected by Herpes Zoster virus. Homeopathy is effective in reducing the intensity and frequency of the pain. In some cases, the pain is persistent and present for months or years, even after the herpetic lesions have subsided. Pain persists for more than 90 days and is termed post-herpetic neuralgia. Homeopathy helps in managing the symptoms of post-herpetic neuralgia and provides relief to the individual.
