Post-Herpetic Neuralgia (Shingles): Causes, Diagnosis, and Treatment
Overview
What Is Post-Herpetic Neuralgia?
Post-Herpetic Neuralgia is a complication of shingles that causes long-lasting nerve pain in the area affected by the viral rash. While shingles itself typically resolves within a few weeks, PHN can persist for months or even years, especially in older adults or those with weakened immune systems.
The pain results from damage to the sensory nerves during the shingles outbreak, leading to abnormal nerve signals and hypersensitivity. Symptoms often include burning, stabbing, or electric shock-like sensations, as well as extreme sensitivity to touch (allodynia). PHN is the most common cause of neuropathic pain in adults following shingles (Dworkin et al., 2017).

Expert Analysis
Understanding Post-Herpetic Neuralgia: Signs And Symptoms
Symptoms of PHN typically occur in the same area where the shingles rash appeared and include:
- Persistent burning or aching pain that can be severe and debilitating
- Sharp, stabbing, or electric shock-like sensations
- Sensitivity to light touch, often making clothing or bedding painful
- Numbness or tingling in the affected area
- Sleep disturbances due to ongoing discomfort
- Possible muscle weakness in severe cases
The pain may begin shortly after the shingles rash resolves or appear weeks later. It often interferes with daily activities, mood, and sleep, significantly affecting quality of life (Dworkin et al., 2017).

What Causes Post-Herpetic Neuralgia?
PHN is caused by nerve damage during a shingles outbreak, which occurs when the varicella-zoster virus reactivates in the nerve roots near the spinal cord or brain. The virus inflames and damages these nerves, disrupting normal pain signaling.
Risk factors include:
- Age over 60, with increased risk as age advances
- Severity and duration of the initial shingles rash
- Weakened immune system
- Presence of intense pain during shingles infection
Not everyone who gets shingles develops PHN, but the risk increases with age and other health factors (Dworkin et al., 2017).

Evaluation
How We Diagnose Post-Herpetic Neuralgia
Diagnosis is primarily clinical, based on the history of shingles and persistent pain in the affected dermatome (skin area supplied by the damaged nerve). A thorough physical exam assesses sensory function and pain patterns. Imaging or nerve studies may be used to exclude other causes of neuropathic pain.
Early diagnosis helps tailor an effective treatment plan to minimize pain and prevent complications (Dworkin et al., 2017).
