I fell this morning on a run to work. I put out my hands to catch the fall, but still hit my chin requiring 4 or 5 stitches. Later today at lunch time, I had difficulty chewing. I had pain on the left side of my jaw just below the ear. As I finished my lunch the pain decreased, but at supper I started out with the pain again. Should I put alternate hot and cold packs on it? The jaw does not appear broken, but maybe a little misaligned. What do you suggest? My wife wonders about TMJ.
