What is Post-Herpetic Neuralgia?

Post Herpetic Neuralgia (PHN) is a persistent and often debilitating neuropathic pain condition that arises as a complication of shingles, caused by the varicella-zoster virus. Shingles presents as a painful rash or blisters on the skin, usually affecting specific areas like the trunk or face. Even after the rash heals, individuals may experience lingering pain along the affected nerve pathway, known as post herpetic neuralgia. This chronic pain can persist for weeks, months, or even years, significantly impacting the person's quality of life.

Why Do I Have Post Herpetic Neuralgia?

Post Herpetic Neuralgia (PHN) develops when the varicella-zoster virus damages nerve fibres during the initial shingles outbreak. Even after the rash disappears, the virus may remain dormant in nerve tissue near the spinal cord and reactivate later in life, leading to nerve damage and chronic pain. Older adults and individuals with weakened immune systems are at higher risk of developing PHN. The pain associated with PHN is thought to result from nerve damage or irritation during the shingles episode, causing persistent discomfort even after the rash has resolved.

How Do I Know If I Have Post Herpetic Neuralgia?

Post Herpetic Neuralgia (PHN) is characterized by persistent pain in the area where shingles occurred, even after the rash has cleared. The pain is often described as burning, stabbing, or shooting, and it may be accompanied by heightened sensitivity to touch. PHN can significantly impact daily activities and quality of life, making it important to seek medical evaluation if experiencing persistent pain after shingles. If you've had shingles and continue to experience pain in the previously affected area, you may have Post Herpetic Neuralgia. PHN is diagnosed based on your medical history, the presence of a prior shingles episode, and the persistence of pain beyond the healing of the rash.

Can Anything Be Done to Help My Post Herpetic Neuralgia?

Treatment for post herpetic neuralgia (PHN) aims to alleviate pain and improve quality of life. Medications such as anticonvulsants, antidepressants, and topical agents may be prescribed to help manage neuropathic pain. Additionally, nerve blocks, transcutaneous electrical nerve stimulation (TENS), and physical therapy techniques can provide relief for some individuals. Various approaches may be utilised often in combination with a collaborative multidisciplinary care plan to provide a holistic approach to managing PHN At NCOFP, Dr. Neysan Chah and our team specialise in comprehensive care for orofacial pain conditions, including post herpetic neuralgia.
