It is the most common cause of rapid onset testicular pain and swelling in people under 18 years old. It occurs in about 1 in 4,000 to 1 per 25,000 males per year before 25 years of age; but it can occur at any age, including infancy. : 149

"Narcissistic injury and narcissistic scar are terms used by Freud in the 1920s. Narcissistic wound and narcissistic blow are other, almost interchangeable, terms. When wounded in the ego, either by a real or a perceived criticism, a narcissistic persons displays of anger can be disproportionate to the nature of the criticism suffered; but typically, the actions and responses of the NPD person are deliberate and calculated. Despite occasional flare-ups of personal insecurity, the inflated self-concept of the NPD person is primarily stable.In The Psychology of Gambling (1957), Edmund Bergler considered megalomania to be a normal occurrence in the psychology of a child, a condition later reactivated in adult life, if the individual takes up gambling. In The Psychoanalytic Theory of Neurosis (1946), Otto Fenichel said that people who, in their later lives, respond with denial to their own narcissistic injury usually undergo a similar regression to the megalomania of childhood. Narcissistic supply
Narcissistic supply was a concept introduced by Otto Fenichel in 1938, to describe a type of admiration, interpersonal support, or sustenance drawn by an individual from his or her environment and essential to their self-esteem. The term is typically used in a negative sense, describing a pathological or excessive need for attention or admiration in codependents and the orally fixated, that does not take into account the feelings, opinions, or preferences of other people.
