There is also the question of a pain threshold, or the point when a stimulus is perceived as pain, and pain tolerance, or the intensity and duration a person can endure before outwardly responding.
The pain threshold does not vary significantly among people, or in the same person over time.
Pain tolerance can be conditioned by a number of factors, such as culture, role behavior, physical and emotional health, pain experiences, and expectations.
Pain tolerance can be reduced or increased by a number of different factors.
