בלילה הייתה לי צמרמורת, ולכן הרופאה שלחה אותי לעשות בדיקת דם.

בלילה means at night or during the night.

It is made from:

• ב־ = in / at
• לילה = night

So בלילה literally means in the night, but in natural English it is usually at night.

Hebrew often puts a time expression near the beginning of the sentence, just like English can do with At night, ... or During the night, ....

Hebrew often uses a structure that literally looks like There was to me a chill to express I had chills / I got chills.

So:

• הייתה = was
• לי = to me
• צמרמורת = chill / shivering / goosebumps-like chill

This is a very natural Hebrew way to express a physical sensation or condition. It is similar to patterns like:

• יש לי חום = I have a fever
• יש לי כאב ראש = I have a headache

So even though English might prefer a verb like I shivered, Hebrew often uses there was / I had type wording here.

Because צמרמורת is a feminine singular noun.

In this kind of Hebrew sentence, the verb often agrees with the thing being experienced, not with the person experiencing it. So the grammar is built around צמרמורת:

• צמרמורת = feminine singular
• therefore הייתה = feminine singular was

That is why it is הייתה לי צמרמורת and not היה לי צמרמורת.

לי means to me.

It is the preposition ל־ (to / for) plus the pronoun ending for me.

In this sentence, לי is used in a very common Hebrew pattern to express possession or experience:

• הייתה לי צמרמורת = literally a chill was to me
• natural English: I had chills or I got a chill

So לי does not mean me as a direct object here. It means to me, which Hebrew uses where English often says I had.

צמרמורת usually refers to a physical chill, shiver, or shuddering feeling. Depending on context, it can be translated as:

• a chill
• shivering
• chills
• sometimes even goosebumps, though that is not always the best translation

Grammatically, it is a feminine singular noun. Even if English often says chills in the plural, Hebrew commonly uses the singular צמרמורת.

ולכן means and therefore, and so, or therefore.

It is made of:

• ו־ = and
• לכן = therefore / so

It connects the two parts of the sentence logically:

• first: there was a chill / I had chills at night
• then: as a result, the doctor sent me for a blood test

It sounds a little more formal or written than just אז (so), though it is still very common and natural.

הרופאה means the female doctor.

Breakdown:

• ה־ = the
• רופאה = female doctor

The masculine form is רופא.

Since the sentence specifically uses the feminine noun, the following verb also has to be feminine:

• הרופאה שלחה = the female doctor sent

If the doctor were male, it would be:

• הרופא שלח אותי...

Because the subject is הרופאה, which is feminine singular.

Hebrew verbs in the past tense agree with the subject in gender and number:

• הרופאה שלחה = the female doctor sent
• הרופא שלח = the male doctor sent

So שלחה is simply the correct past-tense form for a feminine singular subject.

אותי means me as a direct object.

So:

• שלחה אותי = sent me

This is different from לי, which means to me.

Compare:

• הייתה לי צמרמורת = I had chills / literally there was a chill to me
• שלחה אותי = sent me

So the sentence uses two different pronoun forms because they have two different grammatical jobs:

• לי = indirect/dative idea, to me
• אותי = direct object, me

Yes, literally it means to do a blood test, but in natural English we would usually say to get a blood test or to have a blood test done.

In Hebrew, לעשות (to do / to make) is very commonly used with tests, checks, procedures, and similar actions:

• לעשות בדיקה = to do / have a test
• לעשות צילום = to do / have an X-ray
• לעשות ניתוח = to do / undergo surgery, depending on context

So even if do sounds slightly odd in English, it is very idiomatic in Hebrew.

Because בדיקת דם is a construct chain in Hebrew, called סמיכות.

The first noun changes form:

• בדיקה = test / examination
• בדיקת = test of ...
• דם = blood

So:

• בדיקת דם = blood test
  literally: test of blood

This is a very common Hebrew structure. Similar examples:

• כוס מים = a glass of water
• בית ספר = school (literally house of book historically)

So בדיקת דם is the normal and correct way to say blood test.

Yes. Both are possible, but they are slightly different in structure.

• שלחה אותי לעשות בדיקת דם = she sent me to do / get a blood test
• שלחה אותי לבדיקת דם = she sent me for a blood test

The second version is a bit more compact. The version in your sentence is also very natural and makes the action more explicit.

Not completely. Hebrew word order is fairly flexible, especially with time expressions like בלילה.

For example, these are all possible in different contexts:

• בלילה הייתה לי צמרמורת...
• הייתה לי צמרמורת בלילה...

The version with בלילה first gives it a bit more emphasis, like During the night, I had chills.

The main thing that stays clear is the grammar:

• הייתה matches צמרמורת
• שלחה matches הרופאה
• אותי is the object of שלחה

So the order can move somewhat, but the original sentence is very natural.

Because ולכן introduces the result of the first clause.

The sentence has two connected parts:

1. בלילה הייתה לי צמרמורת
2. ולכן הרופאה שלחה אותי לעשות בדיקת דם

The comma helps show the pause and the cause-result relationship:

• first, the symptom
• then, the consequence

In modern Hebrew writing, this comma is very normal before a connector like ולכן.
