Pain is always a personal experience that is influenced to varying degrees by biological, psychological, and social factors.
Pain and nociception are different phenomena. Pain cannot be inferred solely from activity in sensory neurons.
Through their life experiences, individuals learn the concept of pain.
A person’s report of an experience as pain should be respected.
Although pain usually serves an adaptive role, it may have adverse effects on function and social and psychological well-being.
Verbal description is only one of several behaviors to express pain; inability to communicate does not negate the possibility that a human or a nonhuman animal experiences pain.
