i had pneumonia once and couldn't breathe at night unless I placed myself up against the corner of a wall (when I attempted to lay down it felt like death) So i had to sleep like that for 2-3 days.
Each breath i took actually hurt
I didn't have insurance so I had to walk it off.
I'm sure a collapse lung probably hurts 100x more tho
Not being able to breathe is no joke!
