The verb doler (conjugation) means "to hurt" or "to ache". It is irregular. The "o" changes to "ue" in the present indicative and subjunctive, and in the imperative.

The verb doler is similar to the verb gustar. It is always accompanied by (IOP) indirect object pronouns (me, te, le, nos, os, les).

When you hurt you use the phrase: me duele (singular) or me duelen (plural).

singular
Me duele el cuello.
My neck hurts.

plural
Te duelen mucho las muelas.
Your teeth hurt a lot.

Let's review other examples:
Me duele el estómago.
My stomach hurts.

Les duelen las piernas.
Their legs hurt.

Sometimes, we use the preposition a to reinforce the subject, as in the following pattern:

A + subject + IOP + verb doler

A Ben le duelen los pies.
(To Ben) Ben's feet hurt.

A mí me duele la garganta.
My throat hurts.

A nosotros nos duelen los pies.
Our feet hurt.
