الدوا ده كويس لو راسك بتوجعك.

A natural Egyptian Arabic pronunciation would be:

id-dawa da kwayyis law rāsak bitwaggaʿak

A few notes:

• الدوا → id-dawa or ed-dawa
• ده → da
• كويس → kwayyis / kwayyes
• لو → law
• راسك → rāsak
• بتوجعك → bitwaggaʿak or sometimes bitwigaʿak, depending on speaker

You do not need to pronounce it like Modern Standard Arabic. In Egyptian, this sentence is said in a clearly colloquial way.

الدوا means the medicine or just medicine in everyday Egyptian Arabic.

It comes from دوا meaning medicine/remedy.

In real usage, Arabic often uses the where English would just say a general noun. So الدوا ده can naturally mean this medicine.

Also, in Egyptian Arabic, the word is commonly دوا rather than the more formal Modern Standard Arabic دواء.

Because in Arabic, when you say this + noun, the noun is usually definite.

So:

• الدوا ده = this medicine
• literally: the-medicine this

This is normal Arabic structure. You generally do not say the equivalent of medicine this without the definite article.

In Egyptian Arabic, demonstratives like ده (this, masculine) usually come after the noun.

So:

• الولد ده = this boy
• العربية دي = this car
• الدوا ده = this medicine

This is one of the first word-order differences English speakers notice.

ده means this for a masculine singular noun.

Since دوا is treated as masculine singular, you use ده.

Compare:

• ده = this (masculine)
• دي = this (feminine)
• دول = these

So here, الدوا ده = this medicine.

كويس means good, fine, okay, or effective, depending on context.

In this sentence, كويس means something like:

• good
• good to use
• helpful
• effective

So الدوا ده كويس means this medicine is good or more naturally this medicine is good/helpful.

Because in Arabic, the verb to be in the present tense is usually not stated.

So:

• الدوا ده كويس
• literally: this medicine good
• natural English: this medicine is good

This is completely normal in both Egyptian Arabic and Modern Standard Arabic.

لو means if here.

So:

• لو راسك بتوجعك = if your head hurts

In some contexts, لو can also feel close to when in English, especially in practical advice like this. But the core meaning is if.

راسك means your head.

It is made of:

• راس = head
• -ك = your

So:

• راس = head
• راسي = my head
• راسك = your head
• راسه = his head
• راسها = her head

This is a very common Arabic pattern: possession is often shown by adding a suffix directly to the noun.

Because Arabic often uses attached pronoun suffixes instead of separate words like English my, your, his.

So instead of saying something like head your, Arabic combines them:

• راس
  • ك = راسك = your head

This is one of the most important grammar patterns to get comfortable with in Arabic.

بتوجعك means hurts you or is hurting you.

It comes from the verb وجع related to pain/hurting.

Here it is built like this:

• بـ = present-tense marker in Egyptian Arabic
• تـ... = part of the present-tense conjugation
• وجع = hurt/cause pain
• -ك = you

So راسك بتوجعك is literally something like:

your head is hurting you

That is how Arabic often expresses you have a headache or your head hurts.

That is just a normal Arabic way of expressing bodily pain.

In Egyptian Arabic, body parts often act like the thing causing pain, with the person marked as the one affected:

• بطني بتوجعني = my stomach hurts
• سناني بتوجعني = my teeth hurt
• راسك بتوجعك = your head hurts

Literally, these look like:

• my stomach hurts me
• my teeth hurt me
• your head hurts you

It may feel unusual at first, but it is extremely natural in Arabic.

Yes. In Egyptian Arabic, the form with بـ usually expresses a present or habitual meaning.

So بتوجعك can mean:

• hurts you
• is hurting you

The exact English translation depends on context. In this sentence, English would most naturally say:

This medicine is good if your head hurts.

The sentence is:

الدوا ده كويس لو راسك بتوجعك

Piece by piece:

• الدوا ده = this medicine
• كويس = good
• لو = if
• راسك = your head
• بتوجعك = hurts you

So the full structure is basically:

this medicine good if your head hurts

That is very normal Arabic sentence structure.

Yes. Depending on context, you might translate it as:

• This medicine is good if you have a headache.
• This medicine is good if your head hurts.
• This medicine helps when you have a headache.
• This medicine is good for headaches.

The Arabic sentence itself is simple and everyday, so several natural English versions are possible.

راس definitely means head, and it is very common.

But in Egyptian Arabic, people also very often use دماغ in expressions about headaches or head pain.

For example, you may hear:

• دماغي واجعاني = my head hurts
• راسي بتوجعني = my head hurts

So راسك بتوجعك is correct and natural, but learners should know that Egyptian speakers also use دماغ a lot in everyday speech.

A more formal / Modern Standard Arabic version would be something like:

هذا الدواء جيد إذا كان رأسك يؤلمك

But that is not how people normally speak in everyday Egyptian conversation.

The Egyptian sentence:

الدوا ده كويس لو راسك بتوجعك

is much more useful for daily speech.

Usually no, because عشان normally means because, so that, or sometimes for.

Here you need لو because the meaning is if:

• لو راسك بتوجعك = if your head hurts

If you said عشان راسك بتوجعك, that would shift the meaning toward because your head hurts, which is different.

This sentence is great because it teaches several very common Egyptian patterns:

1. Noun + ده/دي

   • الدوا ده = this medicine
   • البنت دي = this girl

2. No present-tense is

   • الدوا ده كويس = this medicine is good

3. Possessive suffixes

   • راسك = your head
   • راسي = my head

4. Body part + بتوجع + pronoun

   • بطني بتوجعني = my stomach hurts
   • ضهرك بيوجعك = your back hurts

5. لو for if

   • لو تعبان = if you’re tired
   • لو محتاج حاجة = if you need anything

So this one sentence contains several high-frequency everyday structures.
