Complex Regional Pain Syndrome-Like Symptoms Following Herpes Zoster Infection With Distal Extremity Involvement: A Case Report

Background: Complex regional pain syndrome (CRPS)-like symptoms are rarely observed after herpes zoster (HZ) infection. Especially in the presence of a rash spreading to the distal extremity, CRPS-like symptoms are more common. Case Report: In this report, we present a 67-year-old patient who developed CRPS-like symptoms along with persistent severe pain after HZ infection, whose symptoms resolved after sympathetic ganglion blockade. Conclusions: CRPS-like symptoms are rarely to occur after HZ infection, especially in patients with HZ infection affecting the distal extremity. In these cases, early interventional procedures may be effective in resolving clinical symptoms, may affect prognosis, and may help prevent persistent pain.
