Ojalá la hinchazón baje pronto, porque ese yeso le resulta muy incómodo.

Because ojalá is normally followed by the subjunctive when you are expressing a wish, hope, or something uncertain.

So:

• Ojalá la hinchazón baje pronto = Hopefully the swelling goes down soon / I hope the swelling goes down soon

Here, baje is the present subjunctive of bajar.

Compare:

• La hinchazón baja pronto = The swelling goes down soon
  This sounds like a statement of fact.
• Ojalá la hinchazón baje pronto = a wish or hope, so subjunctive is needed.

A very common pattern is:

• Ojalá + subjunctive

For example:

• Ojalá llueva
• Ojalá tengas suerte
• Ojalá se mejore pronto

Ojalá means something like:

• hopefully
• I hope
• let’s hope

It expresses a strong wish or hope.

It is similar in meaning to espero que, but the structure is different:

• Ojalá la hinchazón baje pronto
• Espero que la hinchazón baje pronto

Both are natural, but ojalá often sounds a bit more emotional or more like let’s hope.

Also, with ojalá, you do not add que in this sentence. You simply say:

• Ojalá + subjunctive

Hinchazón means swelling.

It is a feminine noun, so it takes:

• la hinchazón

Even though many nouns ending in -zón are not immediately obvious to learners, you simply have to learn the gender with the word.

This noun comes from the idea of swelling up, related to the verb hinchar(se):

• hinchar = to inflate, to swell something
• hincharse = to swell up

Examples:

• Tengo hinchazón en el tobillo.
• La hinchazón todavía no baja.

So in the sentence, la hinchazón is the subject of baje.

Yes. Baje comes from the verb bajar.

In many contexts, bajar means to go down, to lower, or to decrease. In medical contexts, it is very commonly used for things like:

• swelling
• fever
• inflammation
• pain intensity

So here:

• la hinchazón baje = the swelling goes down / decreases

This is a very natural Spanish way to say it.

Other examples:

• Espero que te baje la fiebre pronto. = I hope your fever goes down soon.
• La inflamación ya está bajando. = The inflammation is already going down.

Yes, here pronto means soon.

So:

• baje pronto = goes down soon

In Spain, pronto is very common and natural in this kind of sentence.

Depending on context, pronto can also suggest fairly soon or before long. It does not literally mean promptly in the English sense here.

Examples:

• Vuelve pronto. = Come back soon.
• Espero verte pronto. = I hope to see you soon.

Because porque here means because, introducing the reason.

• ..., porque ese yeso le resulta muy incómodo.
• ..., because that cast is very uncomfortable for him/her.

This is different from:

• por qué = why
• porque = because
• el porqué = the reason
• por que = a less common combination in other structures

So in this sentence, porque is the normal conjunction meaning because.

Here, yeso means cast.

Literally, yeso is plaster or gypsum, but in everyday Spanish it is also commonly used to refer to a medical plaster cast on an arm, leg, etc.

So in this context:

• ese yeso = that cast

A learner might first think of building material, but in medical situations this is a very normal meaning.

You may also hear more specific expressions like:

• yeso en la pierna
• llevar yeso
• poner un yeso

All of these relate to having a cast.

Both este and ese can mean this/that, but the choice depends on how the speaker is mentally positioning the object.

Very roughly:

• este = this, closer to the speaker
• ese = that, a bit more removed, often linked to the listener or to something already mentioned
• aquel = that over there, more distant

In this sentence, ese yeso can sound like that cast in the sense of that cast you’re wearing / that cast we’re talking about.

Spanish often uses ese where English might still use this, depending on perspective. So do not try to map them too mechanically.

Literally, it is something like:

• it results very uncomfortable to him/her

But in natural English, that becomes:

• it is very uncomfortable for him/her
• he/she finds it very uncomfortable

Breakdown:

• le = to him / to her / to you (formal)
• resulta = turns out to be / is / proves to be
• muy incómodo = very uncomfortable

So:

• ese yeso le resulta muy incómodo
  = that cast is very uncomfortable for him/her
  or
  = he/she finds that cast very uncomfortable

This structure is common in Spanish when talking about how something feels or seems to someone.

Le is an indirect object pronoun meaning:

• to him
• to her
• to you (formal singular)

It refers to the person affected by the discomfort.

So:

• ese yeso le resulta muy incómodo

means that the cast is uncomfortable for that person.

Spanish often uses an indirect object pronoun where English uses a phrase like:

• for him
• for her
• to me
• to them

Examples:

• Este sofá me resulta cómodo. = This sofa is comfortable for me / I find this sofa comfortable.
• La idea les resulta extraña. = The idea seems strange to them.

Without more context, le could refer to a man, a woman, or you in a formal context.

Because incómodo agrees with yeso, not with the person referred to by le.

• yeso is masculine
• therefore: incómodo

So the structure is:

• ese yeso → masculine singular
• resulta muy incómodo

If the noun were feminine, the adjective would change:

• esa férula le resulta muy incómoda

Even though le may refer to a woman, the adjective still agrees with the thing being described, not the person experiencing it.

You could say:

• ese yeso es muy incómodo

and that is grammatically correct.

But resulta adds a nuance. It often sounds like:

• turns out to be
• is proving to be
• is found to be
• comes across as

So:

• ese yeso le resulta muy incómodo

can suggest the experience of the person wearing it: they find it very uncomfortable.

This is often more natural when talking about someone’s personal experience or reaction.

Compare:

• Ese yeso es muy incómodo. = a more direct description
• Ese yeso le resulta muy incómodo. = it feels very uncomfortable to him/her; he/she finds it very uncomfortable

The sentence has two parts:

1. Ojalá la hinchazón baje pronto
2. porque ese yeso le resulta muy incómodo

Breakdown:

First part

• Ojalá = hopefully / I hope
• la hinchazón = the swelling
• baje = goes down / decreases (subjunctive)
• pronto = soon

Second part

• porque = because
• ese yeso = that cast
• le = to him/her
• resulta = is / proves / feels
• muy incómodo = very uncomfortable

So the logic is:

• Hopefully the swelling goes down soon, because that cast is very uncomfortable for him/her.

This sentence is already natural Spanish, but a learner may wonder about alternatives. Some common ones are:

• Ojalá se le baje pronto la hinchazón, porque ese yeso le resulta muy incómodo.
• Espero que la hinchazón baje pronto, porque ese yeso le resulta muy incómodo.
• A ver si baja pronto la hinchazón, porque ese yeso le molesta mucho.

These have slightly different tones:

• Ojalá... = hopeful, a bit emotional
• Espero que... = straightforward I hope that...
• A ver si... = let’s see if... / hopefully..., more colloquial
• le molesta mucho = it bothers him/her a lot, a slightly different idea from is uncomfortable

So the original sentence is perfectly good, but there are several natural ways to express the same idea.
