بعد ما استعملت الكريم يومين، صار كتفي احسن وصرت امشي منيح.

In Levantine, بعد ما is a very common way to say after before a full verb phrase.

• بعد = after
• بعد ما استعملت = after I used

Here, ما is not a negation word. It is just part of the connector بعد ما.

So:

• بعد ما استعملت الكريم = after I used the cream

This is much more natural in everyday Levantine than trying to build the sentence in a more formal Arabic style.

استعملت can mean different things depending on context, because several past-tense forms look the same in Levantine spelling.

It can be:

• I used
• you used (masculine singular)
• sometimes also you used (feminine singular), depending on dialect/pronunciation

In this sentence, the later verb صرت امشي clearly shows the speaker is talking about themselves, so استعملت here means I used.

So the meaning is:

• بعد ما استعملت الكريم = after I used the cream

Context often tells you who the subject is.

Yes. يومين here means for two days.

In Levantine, a duration often comes directly after the verb or after the object:

• استعملت الكريم يومين = I used the cream for two days

So يومين is not the object. The object is الكريم.
يومين tells you the length of time.

This is very natural word order in spoken Arabic.

يومين is the dual form meaning two days.

In spoken Levantine, the dual usually appears as -ين:

• يوم = a day
• يومين = two days

You do not need اثنين here.
So:

• يومين by itself already means two days

Also, forms like يومان belong more to formal Arabic / MSA, not everyday Levantine speech.

Literally, it is something like:

• my shoulder became better

Breakdown:

• صار = became
• كتفي = my shoulder
• احسن = better

So Levantine often uses صار where English might use got or became:

• صار كتفي احسن = my shoulder got better / my shoulder became better

This is a very common way to talk about a change of condition.

Because Arabic usually adds possessive endings directly to the noun.

• كتف = shoulder
• كتفي = my shoulder

The -ي ending means my.

Other examples:

• بيتي = my house
• إيدي = my hand
• ظهري = my back

So كتفي is a single word meaning my shoulder.

They are related, but they are not used the same way.

• احسن = better
• منيح = well / good

In the sentence:

• صار كتفي احسن = my shoulder got better
• صرت امشي منيح = I started walking well

So:

• احسن is comparative: better
• منيح describes the quality of something: good / well

You would not normally switch them here.

Yes. They are forms of the same verb, صار, which often means became.

Here are the two forms:

• صار = he/it became
• صرت = I became

In the sentence:

• صار كتفي احسن = my shoulder became better
  
  • كتفي is treated like it, so the verb is صار
• صرت امشي منيح = I became / started to walk well
  
  • now the subject is I, so the verb is صرت

So the verb changes because the subject changes.

Because after صار / صرت, Levantine often uses the imperfect verb to express a new state or ability.

• صرت امشي = I came to walk / I started being able to walk / I ended up walking

This structure is very common:

• صرت افهم = I started to understand
• صار يحكي عربي = he started speaking Arabic
• صارت تمشي منيح = she started walking well

Using صرت مشيت would sound wrong here. After صرت, you usually want the imperfect form, not the past.

Good question. In Levantine, the b- prefix often marks regular or present actions:

• بمشي = I walk / I am walking / I usually walk

But after verbs like صار / صرت, the imperfect often appears without b-:

• صرت امشي = I started to walk / I became able to walk

So:

• امشي here is the expected form after صرت
• صرت بمشي may sometimes be heard in some contexts or dialect habits, but صرت امشي is the standard and most natural pattern for this meaning

Here it means well.

• امشي منيح = walk well

In Levantine, منيح can correspond to English good or well, depending on context.

Examples:

• هالشي منيح = this is good
• أنا منيح = I’m good / I’m fine
• بيحكي منيح = he speaks well

So in your sentence, because it describes how the person walks, the best English meaning is well.

Yes, استعملت الكريم is natural and common.

But Levantine speakers might also use:

• حطّيت الكريم = I put on the cream
• دهنت الكريم or دهنت حالي بالكريم = I applied / spread the cream

The difference is:

• استعملت الكريم focuses on using the cream
• حطّيت الكريم focuses on putting it on
• دهنت focuses more on applying/spreading it on the body

So the sentence is fine and natural, but there are other common ways to say something similar.

Normally, no. In this sentence, it is understood as:

• after I used the cream for two days

That is because يومين comes with the verb استعملت as a duration expression.

If you wanted to say two days after I used the cream, you would usually need a clearer structure, such as something more like:

• بعد يومين من استعمال الكريم...
• or another phrasing that clearly separates two days later

So in your sentence, يومين belongs with استعملت and means for two days.

Yes, it strongly sounds like spoken Levantine.

Clues include:

• بعد ما as a spoken connector
• منيح = a very common Levantine word for good/well
• simple spoken-style sequencing with صار and صرت

A more formal MSA-style sentence would look quite different in vocabulary and structure.

So this is the kind of sentence you would expect in everyday conversation, not in formal writing.

Yes, several very useful Levantine patterns appear here:

1. بعد ما + past verb

   • بعد ما وصلت = after I arrived
   • بعد ما خلصت = after I finished

2. verb + duration

   • اشتغلت ساعة = I worked for an hour
   • نطرت يومين = I waited for two days

3. صار / صرت + adjective for change of state

   • صار أحسن = it got better
   • صرت تعبان = I became tired

4. صار / صرت + imperfect verb for starting or becoming able to do something

   • صرت افهم = I started to understand
   • صار يمشي = he started walking

So this one sentence contains several very high-frequency spoken patterns.
