I did it twice, one year apart. It was said that the large nerve removed during the first procedure could grow, so I had to do another retouch, so I did it again a year later. I did it under partial anesthesia, but it didn't hurt because of the anesthesia, and it was like going back and forth with a large needle inside, and it hurt so much when I removed it.
However, I haven't really seen any effect after doing it.. It's been 2 years since I did it now, and I haven't seen any muscle loss when I touch my jaw.
I'm comforting myself with the hope that it will be okay...
I'm worried about square jaw surgery in 2 weeks.
