Salen entre las v\u00e9rtebras y viajan por todo el cuerpo: forman el nervio ci\u00e1tico, que baja por el gl\u00fateo, el muslo, la pantorrilla y llega hasta los dedos del pie. Cuando algo comprime esos nervios en su origen \u2014dentro de la columna\u2014, el dolor viaja por todo el trayecto del nervio, como si fuera un cable pelado que da corriente en cualquier punto del recorrido.<\/p>\n\n    <!-- Sciatic nerve path illustration -->\n    <div class=\"illus-wrap\">\n      <div class=\"illus-label\">\ud83d\udcd6 Cuaderno M\u00e9dico \u2014 Recorrido del Nervio
