Hurting yourself, sometimes called self-injury, is when a person deliberately hurts his or her own body. Some self-injuries can leave scars that won’t go away, while others leave marks or bruises that eventually will go away. These are some forms of self-injury:
cutting yourself (such as using a razor blade, knife or other sharp object to cut the skin)
punching yourself or other objects
burning yourself with cigarettes, matches or candles
