Eight patients accept the intervention and completed all follow‐ups. Most patients report immediate pain relief after injection, one patient has a mild to moderate dizzy symptom after injection. No other short‐ or long‐term adverse events occurred. For primary outcome, all patients have a timely reduced pain intensity, with no PHN events occurred, as all patients report pain intensity ≤3 in the VAS scale in 3 months after treatment. For electrical pain threshold, we identify that fat grafting differentially increases sensation and pain threshold in HZ area and healthy skin of patients. Besides, our results indicate significant improvement in patients’ life quality decrease in analgesic consumption.
