You got punched in the face and you have an inner bump your chin now smile is Crockett what this?

This is likely a hematoma, which is a collection of blood that forms outside of a blood vessel after it has been damaged. It is commonly known as a 'bruise'. Hematomas can occur anywhere in the body, including the face and chin. Symptoms may include swelling, pain, tenderness, bruising, and changes in skin color. Treatment typically involves rest, ice, compression, and elevation (RICE). Rarely, medical intervention may be necessary if the hematoma is large, causing significant pain, or compressing nearby structures.
