אם עדיין כואב לך הראש, כדאי לקבוע תור אצל הרופא.

This is a very common Hebrew pattern for physical sensations.

In Hebrew, things like pain are often expressed with:

• כואב לי = it hurts me / I have pain
• כואב לך הראש = your head hurts / your head is hurting

So לך literally means to you, but in English we usually translate it more naturally as your in this kind of sentence.

The structure is often:

• כואב + ל־someone + body part

Examples:

• כואבת לי הבטן = my stomach hurts
• כואב לו הגב = his back hurts
• כואבות לי הרגליים = my legs hurt

This is just the normal Hebrew way to talk about many kinds of pain.

Because כואב agrees with the thing that hurts: הראש.

• ראש is grammatically masculine singular
• so the verb/adjective form is כואב

Compare:

• הראש כואב = the head hurts
• הבטן כואבת = the stomach hurts
• הרגליים כואבות = the legs hurt

So the form changes according to the noun that is hurting, not according to the person in לך.

אם means if.
עדיין means still.

So:

• אם עדיין כואב לך הראש = if your head still hurts

Notice that עדיין is an adverb, and it is placed before כואב here. That is a very natural position.

You may also hear slightly different word orders in Hebrew, but this one is standard and natural.

Yes. That is also understandable and natural.

Hebrew word order is more flexible than English. Both of these work:

• אם עדיין כואב לך הראש
• אם הראש עדיין כואב לך

The original version is especially natural in everyday speech because Hebrew often starts this kind of expression with כואב ל־....

So the sentence is not strange; it is a very Hebrew way to say it.

כדאי means something like:

• it’s כדאי = it’s advisable
• it’s a good idea
• you should
• it’s worth

It is commonly followed by an infinitive:

• כדאי ללכת = it’s a good idea to go
• כדאי לבדוק = it’s worth checking
• כדאי לקבוע תור = it’s advisable to make an appointment

So כדאי לקבוע תור means it’s a good idea to schedule an appointment.

A useful thing to know: כדאי does not change for gender or number in normal use. It stays כדאי.

Literally, לקבוע means to set, to arrange, or to fix.
תור means turn, queue, or in this context appointment.

Together, לקבוע תור means:

• to make an appointment
• to schedule an appointment

This is the normal Hebrew expression for arranging a doctor’s appointment, dentist appointment, etc.

Examples:

• אני צריך לקבוע תור לרופא = I need to make a doctor’s appointment
• קבעת תור? = Did you make an appointment?

Great question. Both can appear in medical contexts, but they are not exactly the same.

אצל הרופא literally means at the doctor’s place / with the doctor.
In this sentence, it means an appointment with the doctor.

So:

• לקבוע תור אצל הרופא = to schedule an appointment with the doctor

You can also hear:

• לקבוע תור לרופא

That often means to schedule a doctor’s appointment too, and in everyday speech many people use both.

But אצל הרופא emphasizes the visit being with / at the doctor.

Also, אצל is a very useful preposition:

• אני אצל חבר = I’m at a friend’s place
• היא אצל הרופא = she is at the doctor’s / with the doctor

Hebrew often uses the definite article in places where English may or may not use it.

Here, אצל הרופא is very natural even when the meaning is general, like with the doctor or at the doctor’s.

It does not necessarily mean a specific doctor already known to both speakers. In Hebrew, this can simply be the normal way to refer to the type of professional involved.

Similarly:

• אני הולך לרופא = I’m going to the doctor
• היא אצל השיניים would be wrong, but אצל רופא השיניים / אצל רופא השיניים שלי is fine depending on context

So do not try to match English article usage exactly; Hebrew often handles this differently.

לך is the preposition ל־ (to) plus the pronoun you in the singular.

Here are the singular forms:

• לי = to me
• לך = to you (masculine singular, and in unpointed writing also feminine singular)
• לו = to him
• לה = to her

In this sentence:

• כואב לך הראש = your head hurts

You can swap the pronoun:

• כואב לי הראש = my head hurts
• כואב לו הראש = his head hurts

In everyday unpointed Hebrew, לך can mean either masculine or feminine to you. The pronunciation differs:

• masculine: lekha
• feminine: lakh

But the spelling is usually the same without vowel marks.

Yes, grammatically הראש is the thing that is hurting, so it controls the form כואב.

That is why:

• הראש → masculine singular → כואב
• הבטן → feminine singular → כואבת
• העיניים → plural → כואבות

At the same time, לך marks the person experiencing the pain.

So the clause has two important parts:

• הראש = what hurts
• לך = who it hurts to

This can feel different from English, but once you get used to it, it becomes very natural.

Because Hebrew often expresses recommendation impersonally with כדאי instead of a direct you should form.

So:

• כדאי לקבוע תור = it’s advisable to make an appointment

In context, English often translates this as:

• you should make an appointment

Hebrew does have stronger ways to say you should, for example:

• אתה צריך לקבוע תור = you need to make an appointment
• את צריכה לקבוע תור = you need to make an appointment

But כדאי sounds softer and more like advice than obligation.

It is completely natural in both everyday spoken Hebrew and standard written Hebrew.

Nothing in it sounds unusually formal or literary. In fact, this is exactly the kind of sentence you might hear in normal conversation:

• אם עדיין כואב לך הראש, כדאי לקבוע תור אצל הרופא.

It sounds like calm, practical advice.

A speaker might also say slightly more casual versions, such as:

• אם עדיין כואב לך הראש, אולי כדאי לקבוע תור לרופא.
• אם הראש עדיין כואב, כדאי ללכת לרופא.

But the original sentence is very normal and idiomatic.

Yes. תור has a few related meanings, and that can confuse learners.

Common meanings include:

• queue / line
• turn
• appointment

Examples:

• יש תור ארוך בסופר = there’s a long line at the supermarket
• עכשיו תורך = now it’s your turn
• יש לי תור לרופא = I have a doctor’s appointment

In the sentence לקבוע תור אצל הרופא, the meaning is clearly appointment because of the medical context.
