referred pain
Quick Summary
Referred pain is pain felt in a location different from its origin, typically from internal organs to the body wall. This occurs because nerve fibers from visceral (internal organ) and somatic (body wall) tissues converge on the same areas of the spinal cord and brain. The brain interprets these signals as coming from the more familiar somatic tissues, leading to the mislocalization of pain. For example, heart pain (angina pectoris) can be felt in the chest and arm. Referred pain is always perceived as originating from a superficial area when the actual source is deeper.1

…the superficial tissues is called referred pain. Though the precise mechanism is unclear, that phenomenon may result from the convergence of nerve fibres from different tissues onto the same portion of the spinal cord, which could allow nerve impulses from one pathway to pass to other pathways.
