my 10 yr old daughter was at a camp today @noon, feel off an obstacle course flat on her back, got the wind knocked out of her. Came home later and said fine, went to dance class and came home and was really cranky and said spine hurt, then started to hyperventilate from pain of breathing in her chest and upper back. Gave children's motrin and she slept, but keeps waking saying hurts so much to breathe. She can take a deep breathe, but hurts so much.
