A Case of Postherpetic Itch Effectively Treated With Pulsed Radiofrequency Therapy

We report a case of a 65-year-old female with postherpetic itch (PHI) over the left chest, who experienced significant relief after pulsed radiofrequency (PRF) therapy. While her initial pain and rash had improved with nerve blocks and medications, she had developed severe itching. PRF therapy significantly reduced the itching, which nearly disappeared. This report suggests that neuropathic pain treatments, like PRF, may also be effective for PHI, a condition that is not fully understood and has limited treatment options but can severely impact the quality of life.
