Every now and then Sancho gave vent to deep sighs and dismal groans, and on Don Quixote asking him what caused such acute suffering, he replied that, from the end of his back-bone up to the nape of his neck, he was so sore that it nearly drove him out of his senses.
De cuando en cuando daba Sancho unos ayes profundísimos y unos gemidos dolorosos; y, preguntándole don Quijote la causa de tan amargo sentimiento, respondió que, desde la punta del espinazo hasta la nuca del celebro, le dolía de manera que le sacaba de sentido.
