I'd like to know too.

OP don't mean to hijack your thread but have a question..

I was hit from behind twice in my accident, the first threw my head forward then the second truck that hit me was off the scale throwing my head forward, and hit my head on the steering wheel, (or so I was told as had a contusion and had amnesia)

Can someone have more damage as the hits were so close do you think, always wondered if this is why I have so many problems still?
