We have noticed two errors in our published paper above. Erratum: Correction of Figure In Fig. 3, the name of “Figure by courtesy of Sanho Yi” should be “Sangho Yi.” Erratum: Correction of Table In Table 2, the P-value of VAS score in the Pre-Post 3rd should be revised from 0.03 to 0.3. The revised table is shown below. (Table Presented).
