Was hacking my lungs up for a solid month

AFAIK you can actually have that happen, too. The coughing can not only break ribs and causes vomiting like the other user said, it can cause so much damage to your lungs they start to bleed and you cough up bits of lung tissue.

Absolutely horrifying stuff. Even worse when it's small children and babies who get it. Makes me absolutely enraged we have a fucking miracle cure but people refuse to take it because of some bullshit they saw on Facebook.

I got pneumonia when I was a kid cuz I feel in a stream and inhaled water.

If it's as bad as that then, yeah that shit does sound like it sucks.
