What Is Postherpetic Neuralgia?
Postherpetic Neuralgia is a nerve pain condition that can remain after a shingles rash heals. It often causes burning, stabbing, aching, or touch-sensitive pain in the same skin area affected by shingles. The pain follows a nerve pathway and may continue even when the skin looks normal.

Key Takeaways About Postherpetic Neuralgia
- Pain remains after the shingles rash has healed.
- Symptoms often follow the same nerve pathway as the rash.
- Postherpetic Neuralgia isn't the same as ordinary muscle soreness.
How Postherpetic Neuralgia Works
Postherpetic Neuralgia develops when shingles irritates or damages a sensory nerve. The nerve may keep sending pain signals after the rash clears. Those signals can feel like burning, electric shocks, itching, or sharp pain.

Clinicians look at the pain's location, quality, and triggers. Light contact from clothing or bedding may feel painful. A skin area may also feel numb or unusually sensitive. The symptoms often follow a band-like nerve path on one side of the body.
How Nerve Blocks Fit
Nerve blocks can help identify or calm pain signals from a targeted nerve. A clinician considers the painful area, nearby anatomy, and the person's health history before choosing an approach. The block's response can add useful information to the overall pain assessment.
From the Premier Injury Specialists team
When we assess Postherpetic Neuralgia, we map the painful area and ask how touch affects symptoms. We also review the shingles history and separate nerve pain from nearby muscle or joint pain. For nerve blocks, our team focuses on the suspected nerve and the symptoms it may produce.
Postherpetic Neuralgia in Practice: A Real-World Example
A person may have a healed shingles rash along the ribs but still feel burning pain when a shirt touches the skin. During a nerve block evaluation, the clinician connects the pain pattern with the involved nerve area.
