[Chin] Chin surgery swelling, pain

Two types of chin tip + V-line (square jaw x) were performed. Since I have a protruding chin, I underwent osteotomy and even retracted the tip of my chin. By the 2nd to 4th day after the surgery, my face was very swollen, but the tip of my chin got shorter, so I thought I did pretty well, but as the 10th day went by, the tip of my chin and the double chin area? became so hard and swollen that my chin looked like Thanos. Like Hongman Choi... Today is the 12th day, and although it seems to have gotten a little smaller, the swelling that feels like a candy bite, hard chin tip, and double chin swelling still remain. Does it usually swell like this? There is no pain, just a feeling of muscle tension, but there is no discomfort other than when I open my mouth or tilt my head back. I looked it up on the internet and found Biobond? I heard there is such a thing, but I don't want to regret having the surgery with a big decision, but I'm getting more and more anxious ㅠㅠㅠㅠ I'm curious about what those who experienced it were like ㅠㅠ
