The HDSS and VAS demonstrated significant improvement after treatment on the treated side in comparison with the control side. The mean ± SD of the HDSS after 21 weeks were 1.87 ± 0.61 and 3.38 ± 0.49 (P < 0.001) for the treated and the controlled side, respectively. The follow‐up evaluation revealed that 79% of the patients showed a 1 or 2‐score decrease in HDSS. In total, 80% of patients reported more than 50% satisfaction at the end of the study. Histopathological findings showed a decrease of the number of the sweat glands in the treated side, confirming the above findings.
Treatment of PAH with FMR as a non‐invasive modality can be a safe option with positive therapeutic effects on HDSS without any long‐lasting side effects.
