My friend s little boy is in a wheelchair. The apartment complex doesn t have wheelchair access so he normally gets carried up and down the stairs while in his chair. Well I was carrying him up the concrete stairs and my foot got caught on the top step which caused me to drop the chair with him in it. The chair rolled down a step and fell forward. He ended up cutting up his chin, lips and nose. His chin required stitches. He didn t hit his head at all but is it possible he could have a head or brain injury? He never lost conciousness.
