Post-herpetic neuralgia often develops as a result of shingles. Shingles is caused by a chicken pox virus which largely remains dormant in the immune system, but can flare up, leading to painful rashes and blisters on the skin. Although these rashes typically subside after multiple weeks, oftentimes the pain sensations associated with these rashes remain behind, leading to post-herpetic neuralgia. Common symptom management therapies for post-herpetic neuralgia range from medications, cognitive behavioral therapy, lidocaine patches, NSAIDs, and more.
