Hard to breath or difficulty breathing?

Question

My nose is running. I am hard to breath through nose.

My nose is running. I have a difficulty breathing through nose.

Which is the correct adjective to describe that you have a runny nose.

Answer 1

Both could be OK with some editing:

My nose is running. It is hard to breathe through my nose.
My nose is running. I have/am having difficulty breathing through my nose.

A possessive pronoun is usually used when describing someone's body parts.

As a note: Some people might use a difficulty, though I wouldn't.

Answer 2

In everyday conversation, I think I'd say it something like this:

My nose is running; it's hard for me to breathe through my nose.

or even:

My nose is running; I can't breathe through my nose.

(In the latter case, "I can't breathe" is being used to mean, "I'm having trouble with breathing" – it doesn't necessarily have the more literal meaning of being unable to breathe through my nose at all. English is tricky like that.)

Difficulty is a more formal word that; normally, I'd be less likely to use it except in a more formal context. For example, a doctor might ask a patient:

Are you having any difficulty breathing through your nose?

Answer 3

For me, difficulty breathing and hard to breathe are too general to capture the just the sense of My nose is running. Instead, except perhaps in the most formal contexts, I would simply use runny.

My nose is running. I have a runny nose.
