Background
a dermatomal, Herpes zoster, pain
COMPLICATION, HERPES ZOSTER
Herpes zoster (HZ)‐related pain, characterized by chronic and persistent pain with a dermatomal distribution, is a relatively common complication of HZ. Pulsed radiofrequency (PRF) can effectively relieve HZ‐related pain. There is no study on the effect of the needle tip position in patients with HZ for PRF treatment. This prospective study was conducted to compare two distinct needle tip positions in PRF for HZ‐related pain.
