Hi,
I just hit the top of my heard, hard, emptying the trash in an area when I forgot to duck my head. I was wearing a plastic clip in my hair. I walking right in to the wooden roof and hit the top of that clip and the top of my head at the same time. It really hurt at that moment, but the paid subsided Quickly. No blood, no headache, non dizziness, just a dine size soft sport, indention at the top of my head. Should I be concerned?
