What Could Pain In Backbone After An Accident Suggest?

okay,

well,

u see,

i hve ths friend,

n he said he is having this kind of aching at his backbone,

n he said it was because of a acident when he was playing rugby,

n he suddenly tok a wrong a step got a hit in the head,

he said tht his backbone somehow shrinked a little?

n at the tme he couldn't breathe for a moment,

but he didn't faint,

so nw he's having headaches n his backbone seemed to be aching too?

wht do u thnk is hppening to him?
