My 5 year old son fell at school this morning at school. He tripped and landed half in the sand box and half out. His hip bone landed right on the wood side of the sandbox. I received a call from his school saying that he had been walking funny and complaining of pain. When he got home from school at 4:00, he was still in a fair amount of pain. His posture is different due to favouring his soar hip. My question is should I take him to the walk in clinic, or hospital tonight, or wait and see how he feels in the morning.
