chest X-ray, pulmonary function test

My chest X-ray showed hyperinflation and irregular aeration. My pulmonary test estimated my lung age at 30 years older than I am!!!! I have never smoked. I am worried I have COPD or something from the conditions at work. Work is the only place where my chest and eyes burn. If I dust the room or change the filters, my face flushes and I get a metallic taste in my mouth. Has anyone here had lung issues? Tweet
