If you're over 40, and you cough, there's a chance you microtear your lungs. If you cough up blood for weeks, yes... you will increase pulmonary fibrosis (fancy word for lung scars). That's true for every flu you get... but this one is way harder on the lungs than any flu I've ever had. I'm having mild symptoms, but it's been weeks, fevers come and go, and honestly it's like nothing I've ever had before.
