Approximately 10% of adults suffer from severe chronic pain.
By definition, chronic pain is a state of ongoing pain for long
periods after the healing of the initial inciting event. A
fundamental property of chronic pain is the presence of
spontaneous pain, and its presence is the main reason for
subjects seeking medical care. Spontaneous chronic pain
fluctuates in intensity, and unlike other sensory modalities,
these fluctuations are slow and highly salient.
Descriptions of pain are based on verbal reports and pain
scales
Pain conditions are characterized by questionnaires
Both are static measures
Both are purely subjective
