So I was Recently diagnosed with diffuse centrilobular emphysematous change. There are a few thin-walled pulmonary cysts. Mild lower lobe subpleural linear densities. This all is so confusing. Anyone else have this diagnosis? A little concerned about the outlook. I am using Advair and have a rescue inhaler. Oxygen levels range from 90 to 97 typically. Heart rate can go pretty high. Tired, cough, SOB, and chest tightness are worse symptoms. Struggling to understand all of this. Seems like 3 different diagnoses.
