I have had at least one where I did not hit my head along with the several others I have had since that accident. Loose brain syndrome. But all evidence says I hit my head before any other contact on that big one. Then the back of the same side shoulder. Busted collarbone.

And as far as bruising from impacts? I wouldn't know. It was two weeks before I was aware of much of anything re: my body. And those bruises, if they were there would have been far down the list of injuries to be treated and monitored. But they might account for my IC charge nurse not recognizing me a few weeks later. Never thought of that before. I would guess any external bruises would be below the collarbone in the priority list and the collarbone got zero attention until after IC (and set quite distorted).
