Other factors affecting the perceived level of danger and spatial awareness further complicate the model. While the fear-avoidance model may be simplistic for every situation involving fear, discomfort, and/or chronic pain, its effectiveness is generally acknowledged for diagnosing and understanding how humans positively or negatively react to ...
The experience of pain is individualistic and can be suppressed by stress or exacerbated by anticipation. Simple activation of a nociceptor does not always lead to perceived pain, because the latter also depends on the frequency of the action potentials, integration of pre- and postsynaptic signals, and influences from higher or central processes.
Margo McCaffery was an American registered nurse and pioneer of the field of pain management nursing.McCaffery's oft-quoted definition of pain as "whatever the experiencing person says it is, existing whenever and wherever the person says it does", stated as early as 1968, [1]: 375 has become the prevailing conceptualization of pain for clinicians over the past few decades.
Nociceptive pain consists of an adaptive alarm system. [6] Nociceptors have a certain threshold; that is, they require a minimum intensity of stimulation before they trigger a signal. Once this threshold is reached, a signal is passed along the axon of the neuron into the spinal cord.
In other words, the perceived benefits must outweigh the perceived barriers in order for behavior change to occur. [1] [14] Perceived barriers to taking action include the perceived inconvenience, expense, danger (e.g., side effects of a medical procedure) and discomfort (e.g., pain, emotional upset) involved in engaging in the behavior.

The threshold of pain or pain threshold is the point along a curve of increasing perception of a stimulus at which pain begins to be felt. It is an entirely subjective phenomenon. It is an entirely subjective phenomenon.
It is clear from this definition that while it is understood that pain is a physical phenomenon, the emotional state of a person, as well as the context or situation associated with the pain also impacts the perception of the nociceptive or noxious event.
