I just did the most stupid thing. Opened a kitchen cupboard door, bent down to pick something up off the floor, stood up and whacked my head on the door.
There is a dent at the back of my head, about the size of a finger-tip, and it is bleeding but gradually clotting up. It will be hidden by my hair so a scar won't matter. If it is clotting, and I don't feel concussed, just stupid and in pain, can someone just confirm that I don't need to do anything about it?
Ouch.
