7 Aches

You probably know the word "ache". It can be a verb or a
noun, and means "to hurt" or "a pain". We sometimes combine
the word "ache" with parts of the body. For example, if our
back hurts, we say that we have "backache" or "a backache".
We do *not* do this with all parts of the body. For example,
we cannot say that we have a "handache". There are really
only five parts of the body that we combine with "ache".
They are shown below, plus two other words that we use in a
slightly different way.

BACKACHE

EARACHE

HEADACHE

STOMACHACHE

TOOTHACHE

HEARTACHE
We do not use this to mean a *physical* pain in the heart.
Instead, it means an emotional pain. If you "break my heart" I'll have a heartache. Breaking one's heart means to hurt someone emotionally, such as telling your girlfriend you've found someone else you like better.

FACEACHE (British English only) PS I have never heard this term in conversation with my British friends.
This means an ugly or miserable-looking person.
