How do doctors normally treat a bone bruise in a child? plus, can you get a bone bruise without falling and how? my daugther runs in cross-country .

Bruise = patience: A bone bruise is like a scuff mark in a tree's bark. Bone has sensory endings in the layer around the bones surface like the bark of a tree.If you hit it, the blow can trigger the pain receptors & sometimes a reaction at the bones surface. A bump may form with some calcium buildup. A direct or glancing blow can trigger the event. Over time it will heal on its own.
