Efficacy and Safety of Pulsed Radiofrequency of Dorsal Root Ganglion in Elderly Patient Population With Acute and Subacute Zoster‐Related Pain

Herpes zoster (HZ) is typically characterized by a burning, stabbing pain, hyperalgesia, and allodynia. In some patients, despite the lesions resolving, the pain persists and becomes chronic. If the pain continues for more than 6 months after the onset of the pain phase, this condition is called postherpetic neuralgia (PHN). The frequency and severity of PHN increase with advancing age. The pain in PHN can be severe, sometimes resistant to medications, significantly impacting the patients' quality of life. The elderly patient population cannot tolerate the medications due to their side effects. In this situation, interventional pain treatment should be applied in the elderly patient group who have a high risk of developing PHN compared to other age groups.
