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.
|Self-mutilation is often associated with psychiatric disorders that may be caused by chemical imbalances in the brain.|

A psychosocial assessment may also be given to assess a person’s mental capacity, level of distress, and presence of mental illness.
