I hit my chin about 3 weeks ago while skiing, causing me to cut the inside of my bottom lip on my teeth. It bled for about a day, and had stopped completely after two. It hurt at first obviously, but as time passed it seemed to be healing just fine. About two days ago, I felt a little swelling in my chin, and at this point, its a pretty large and painful lump on my chin. I also feel two little hot spots of pain further up on my jawline, about halfway between my ear and my chin, though there is no swelling.. yet. Is it something I ABSOLUTELY need to get checked?
