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.

A doctor will assess whether care needs to be provided right away to treat or prevent further injury.
Psychologic treatment may be done either one-to-one or in a group setting. It is usually aimed at finding and treating the underlying emotional difficulty, trauma, or disorder. It may also include cognitive behavioral therapy.
