I have a friend who experienced a head injury ten days ago - he was was out for a few minutes - but never went to the doctor - he is dizzy - very tired - he appear stiff - I asked him if his neck hurt, he looks like someone who has a stiff neck and turns with is whole body - his gait does not look normal for him - his front two teeth have separated - but he will not go to the doctor - he said he received concussions in high school when he played football - he has no insurance - he said if he goes in that is what they are going to tell him - I am afraid it is serious - because he looks so bad -
