Classification according to Duration

Acute pain is a part of the body's protective system. It acts as a warning signal of imminent or actual damage. In this respect pain has an important function in maintaining or restoring physical integrity.

However, pain may also be experienced occasionally in the absence of any tissue damage, and its intensity may not be in proportion to the original injury. This is called chronic pain.
