Sense: adjective/1
All three terms describe pain felt away from the actual source of injury. 'Radiating' pain spreads outward along a visible nerve path — sciatica radiating from the lower back down the leg is a classic example. 'Projected' pain also follows a nerve distribution and is often used for nerve-root compression, where the pathway is clear and traceable. 'Referred' pain is distinct: it jumps to a distant body part without a visible nerve-path connection, because the injured organ and the area where pain is felt share the same spinal-cord segment. For instance, a heart attack causes pain in the left arm (not the chest) because the heart and the arm share spinal segments C8–T4. In clinical usage, 'referred' is the most specific term for this segmental-crossing phenomenon; 'radiating' is more general and does not imply the same mechanism.

Etymology
From Latin 'referre' (re- 'back' + ferre 'to carry'), literally 'to carry back'. The medical sense of pain felt in a place different from its origin emerged in the mid-19th century as physicians began mapping the phenomenon of visceral pain felt on the body surface.
