[안면윤곽후기] If you know whether it is swollen flesh or bone... please comment.

hello. It has been two months since I had square jaw reduction surgery through an incision inside my mouth. The swelling is almost gone. Both jaw lines are not asymmetrical, but there is a slightly convex protruding part on the left jaw. It is hard when touched. The hospital says it is because the swelling is lumped together, but it feels like bone. I can't tell if it is bone or bone. . I would like to ask for comments from other members who have similar experiences^^
