When I woke up, I had teeth marks on my cheeks and my jaw joint was always in bad shape! So, I wanted to get rid of my square jaw as well, so I just went to a random place and got it done. Maybe that's why it was a factory type. The counselor looked at my jaw muscles, chose the medicine, and went to get the right shape. He said my jaw muscles aren't that big. Anyway . There was no discomfort or anything like that right after getting the shot, but the next day, my jaw was really sore. Seeing that my friend who got it at another hospital also said it only hurt on the second day, I thought it was because some people are sick and some are not, but they are taking the medicine. I endured it and the pain went away after a few hours. After 4 weeks, I felt the change was just a little bit..? I don't think I've noticed much change around me.
