Hello, I was in a car accident 2 day's ago. My daughter and I banged heads, and as a result I have a bump on the left side of my head. I did not think much of this, till the next morning when I blew my nose there was blood mixed in with the mucus. This morning there was blood again, not a whole lot, but it does have my concern especially since it also seems to be from the left side of my nose only. What should I do? thank you, Femmy
