Hello, I have had two diagnosed concussions in the past. My most recent was from jumping and hitting my head on a heavy wooden object. (Recovery time was about 5 months for the 2nd and 1 month for the first)

Ever since I have had anxiety that I am getting treated and am very protective of my head. Today my roommate threw a wad of cash tied with rubber bands at my head. The money probably weighed a pound or two but the impact was hard enough to move my head to the side.

Anyways it has been a couple hours and I don't think I have any symptoms but my anxiety level is high and my head hurts. Was this impact enough to be either concussive or sub-concussive?
