Μετά το χάπι ανακουφίζομαι λίγο, και η γιαγιά μου ανακουφίζεται όταν ακούει ότι όλα είναι καλά.

Greek often drops subject pronouns because the verb ending already shows the person.

• ανακουφίζομαι = I am relieved / I feel relief
• ανακουφίζεται = he/she/it is relieved

So εγώ is not necessary here. You could add εγώ for emphasis or contrast, but the normal neutral sentence does not need it.

It is a middle/passive-form verb. In Modern Greek, many verbs use passive-style endings even when the meaning is not a straightforward English passive.

Here the pair is:

• ανακουφίζω = I relieve someone/something
• ανακουφίζομαι = I am relieved / I feel relief

So the form looks passive, but in English it is often best translated more naturally as I feel relieved or I get some relief.

They are the same verb in different persons.

• ανακουφίζομαι = I am relieved
• ανακουφίζεται = he/she is relieved

In this sentence:

• ανακουφίζομαι refers to I
• η γιαγιά μου ανακουφίζεται refers to my grandmother

So the ending changes to match the subject.

After μετά, Greek uses the accusative.

So:

• μετά το χάπι = after the pill / after taking the pill

Here χάπι is a neuter noun, and in the singular its nominative and accusative forms are the same, so you see το χάπι in both cases.

You may also hear μετά από το χάπι, which can mean the same thing.

Greek uses the definite article very regularly. Here το χάπι means the pill, referring to a specific pill already understood from the context.

English sometimes omits the article in similar phrases, but Greek usually keeps it. So μετά το χάπι is very natural Greek.

Here λίγο means a little / a bit, and it works adverbially, modifying the verb.

So:

• ανακουφίζομαι λίγο = I feel a little relief / I feel a bit better

Putting λίγο after the verb is a very normal word order. Greek word order is flexible, but this placement is natural and neutral.

In standard Modern Greek, possessive words like μου usually come after the noun.

So:

• η γιαγιά μου = my grandmother

Also, Greek normally keeps the article with family words:

• η μαμά μου = my mom
• ο πατέρας μου = my father
• η γιαγιά μου = my grandmother

That article is not optional in normal usage here.

Because this sentence describes a usual / repeated situation.

• όταν + present often means when(ever) in a general sense
  
  • ανακουφίζεται όταν ακούει... = she feels relieved when(ever) she hears...

If you were talking about one future event, Greek would often use:

• όταν ακούσει = when she hears in the future sense

For example:

• Η γιαγιά μου θα ανακουφιστεί όταν ακούσει ότι όλα είναι καλά.

So ακούει fits the idea of something that happens regularly.

ότι introduces a clause meaning that.

So:

• ακούει ότι όλα είναι καλά = she hears that everything is fine

A useful spelling note:

• ότι = that
• ό,τι = whatever / anything that

In everyday Greek, πως can often replace ότι in this kind of sentence.

Because όλα is neuter plural, meaning all things / everything, and καλά agrees with it.

So:

• όλα = neuter plural
• καλά = neuter plural form of καλός

This expression is extremely common in Greek:

• όλα καλά = everything is fine / all good

Even though English often uses singular everything, Greek commonly uses όλα with a plural adjective here.
