Fell and hit my head on my eyebrows.some bruising around one eye. no other symptoms apart from swelling.is that normal?

Normal vs. abnormal: It is not exactly normal to fall, hit one's head, or bruise one's peri-orbital area. However, after falling and hitting one's eyebrow, it often happens that the blood from the bruise spreads downward around the eye, due to gravity, so that within a day there will be bruising on the bottom of the eye area too. It should all self-resolve, but the eyebrow impact point may have a bit of scarring.
