Abstract and Introduction
The traditional construct of acute pain vs chronic pain is arbitrary and obscures fundamental differences in clinical pain phenomena. A more powerful dichotomy between peripherally generated pain and centrally maintained pains can facilitate advances in both pain research and clinical care. We should abandon the temporally based pain classification scheme because it does not accurately reflect the underlying principles inherent in the phenomena of pain.
"The proper management of pain remains, after all, the most important obligation, the main objective, and the crowning achievement of every physician."
