5 days ago....I tripped and fell, with my chin bone hitting a piece of angle iron (on a trailer)...with most of my weight behind it. It was, of course, extremely painful and left what looked like a cut, but never bled. Although it doesn t look that bad from the outside, barely bruised, it is still extrememly sensitive to the touch and now feels as though it has fever...this is probably 2 inches below my knew, with the blow being directly on my chin bone....should I be concerned...seems silly to go to the dr. for a bruise.
