Pain in the liver.
From hepato- (liver, Greek hepar) + -dynia (Greek dynamis, meaning pain or suffering). This is a straightforward medical term combining the Greek word for liver with the Greek suffix for pain.
While hepatodynia is the medical term, people usually just say 'liver pain,' but the Greek-derived term shows how medical language lets doctors communicate precisely about which organ hurts in any language—a doctor in Japan and Brazil can both understand 'hepatodynia' immediately!
