Self-mutilation or self-injury is any form of self-harm inflicted on your body without the intent to commit suicide.

Self-mutilation may be caused by associated psychological problems. Self-mutilation may be done to release emotional pain, anger, or anxiety. It may also be done to rebel against authority, flirt with risk-taking, or feel in control. In some cases, the behavior is outside your emotional control and related to a neurological or metabolic disorder.
