Yesterday, I had a chin surgery with Silly. It was so painful because it was done under local anesthesia that I thought I was going to die. I asked for a small size , but during the surgery, they said a small size was not practical, so they put in a medium size. At the time of the consultation, the small size was perfect. I have a round face, a slightly protruding mouth, and a slightly short chin . I didn't feel stressed about having a chin, so I did it because I thought it would make me look better. But when I called the hospital today and asked about my size, they didn't tell me properly and talked nonsense. I asked them to tell me the size. They say they put in the size that suits them, but they say there is no fixed number of millimeters for the armless arm, but it seems like they are lying by putting in a large size . What should I do? Also, how many millimeters is the normal size? It doesn’t make sense, does it??
