Such injuries may cause substantial bruising, bleeding and skin damage and are often associated with powerful negative emotions such as stress or anxiety. Most often, such self-injury is not preceded by substantial precontemplation and occurs impulsively. Methods of self-injury include cutting, stabbing, severe scratching, and burning of the skin, most often found on the nondominant limb. Other methods include inserting sharp objects under the skin, hair pulling, and carving words or symbols into the skin. Cutting tends to be the most common of self-injuries, estimated as being present in 70% to 90% of individuals engaging in nonsuicidal self-injury. Cuts are often deep enough to cause bleeding and are characterized by a series of parallel lines frequently located over the volar aspect of the upper extremities.
