Pain is the body's most ancient and fundamental alarm system — a signal evolved to warn of tissue damage and motivate protective behavior.

It is not simply a passive transmission of damage signals from injured tissue to the brain; it is an active, dynamic construction of the nervous system shaped by context, memory, emotion, attention, and expectation.
