Association between the Risk of Relapse and the Type of Surgical Procedure for Herpes Zoster-related Pain.

In the treatment of HZ-related pain, the use of PRF is significantly associated with a high short-term recurrence rate. However, compared with RF-TC, PRF results in milder numbness and less intraoperative pain. RF-TC may be a feasible procedure if patients can accept pain relief at the cost of long periods of numbness, whether RF-TC has the value of clinical promotion still needs to be further explored.
