Excruciating → It is formed from "ex-" (meaning out of or from) and "cruciare" (meaning to torture or torment). The word describes a pain that feels as if it is torturing or tormenting someone from within.
Think of pain that comes 'out of' ('ex-') a feeling of being 'tortured' ('cruciare') — that's why excruciating means extremely painful.
