In Spanish if some part of you body hurts you must say:
Me duele (... and then followed by the part of the body)I add a basic vocabulary that can be useful when traveling abroad:
head: la cabeza
neck: el cuello
shoulder: el hombro
back: la espalda
chest: el pecho
estomach: el estomago
hand: la mano
leg: las pierna
foot: el pie
knee: la rodilla
elbow: el codo
nose: la nariz
ear: el oido
eye: el ojo
or simply you can say 'it hurts here!!': 'me duele aqui!!'.
