My Dd was in a little wagon/riding lawnmower accident. She seemed fine, looked like no broken bones or anything. The next day her right arm and fingers were so swollen I took her to the emergency room. 4 x-rays, 3 hours, and one finally but barely noticable bruise on her collar turned out she had a broken bone after all. She never complained once. She cried on a few minutes after the accident. Wouldn't have known she had a broken bone except for the faint bruise! Strong Girl.
