Hi, My 13 year old son took a hard fall on the basketball court 2 days ago. He fell on his left side/lower hip on the hardwood floor, not on top of anyone and no one one fell on top of him. He has pain and soreness, but no bruise or swelling. It s painful to touch. There is discomfort in walking and he can t run or stride. He says it s a little better after 2 days. He is able to squat and bend his leg, but there is pain. Is this just aches and pains that will go away, or could there be a bigger problem?
