呼吸困难

How long have you had difficulty breathing?

Since last week, Doctor.

Is it very bad?

Yes, I feel like I can't get enough air.

What's harder, breathing in or breathing out?

It's harder to breathe in.

Are you short of breath when you are resting or only when you are doing something physical?

A little when I'm resting, but it's worse when I try to do anything physical.

Can you lie flat in bed?

Oh, no.
