Postherpetic neuralgia (PHN) is pain persisting beyond 3 months from rash onset and is the most common complication of herpes zoster (HZ); it is commonly refractory to medication treatment. Available evidence indicates that high-voltage, long-duration pulsed radiofrequency (PRF) to the dorsal root ganglion (DRG) is a novel and effective treatment for this complication. Nevertheless, the effects of this intervention on refractory HZ neuralgia less than 3 months have not been evaluated.
