Hi, our friend s yougest daughter has just been sent to a children s hospital because of sudeen, unexplained bruising all over her body. Yesterday, her parents became slightly worried due to some bruising around her ankles, and today she had a large bruise on the top of one of her feet. While at the local hospital, she began to show bruises all over her body. According to her parents, she has been feeling fine. what could cause the sudden onset of bruising like this? She has not fallen or bumped into anything and the issue of domestic violence definitely does not apply.
