Me duele la espalda. This is a very common useage of the reflexive form - literally "The back hurts me." The conjugated form of "dolor" refers to "la espalda", not to "me." That is why it is conjugated in the third person, not the first.
Me duele el dedo.
Say 'ojala supieras cuanto me duele'
Solo me duele cuando reír.
Estoy muy adolorido
Te quiero tanto bebé que me duele.
I sleep on my back in Spanish is: Yo duermo de espaldas.
Me retracto
Devuelvaselo
i believe its '' herido'' by what my dictionary and prior knowledge says Or 'lastimado' (both as adjectives) Verb: 'hacer mal a'
if it hurts your back to bend over when your back hurts
we say: necesito que vuelvas
If you mean your back as in the part of your anatomy, the spanish word is "espalda" (S-paul-dah)
