The story of the word

Greek ἰσχιαδικός meant suffering in the hip, from ἰσχίον, the hip socket. Late Latin mangled it into sciaticus, and the mangled form is the one that stuck in English and French while anatomists kept ischium for the bone. The nerve is the thickest in the body, running from the lower spine to the foot, which is why a disc pressing on its roots is felt in the calf rather than the back.
