Hello, Five years ago I fell and hit the left edge of my chin on a hard wooden surface. At the time there was no bleeding , or external cut, but a small amount of swelling of the left side of the chin. There was no jaw damage that i am aware if, no fractures i am aware of. I have left it alone for many years in the hope that the small, 0.5x2cm lump of skin would disappear on its own but it has not. On palpating it is non- tender. I am just wondering please what you think it may be? And how to treat this, as it slightly disfigured my chin. Thank you so much for your advice Sincerely Elliot
