The perception of pain is a primal property of the nervous system and inherent to all people. Pain is more than a sensation. It is an "experience" involving the interaction thoughts, emotions, and past experiences leading to sensory and motor responses.61 Acute pain is the primary reason people seek medical attention and the major complaint that they describe on initial evaluation. Chronic pain may be more debilitating than the trauma itself and may become emotionally and physically debilitating.62,63
