Located or occurring outside the spinal cord or spinal column.
From Latin 'extra' (outside) + 'spinal' (relating to the spine, from 'spina' meaning thorn or spine). A medical anatomical term.
Back pain can be spinal (from your vertebrae themselves) or extraspinal (from muscles, ligaments, or nerves nearby)—a doctor's job is figuring out which one, because the treatments are totally different.
