Bruises are usually normal in active, playful children. Bruises which are particularly common include bruises along the shin and elbows in young children. Any unusual amount of bruising or bruising noted in uncommon areas should be evaluated by the doctor at an office visit. A rash that rapidly develops and resembles a severe bruise without a history of injury is potentially serious. You should immediately contact us with this information if your child should develop such a rash.
