I was recently diagnosed with COPD after many trusts due to a high level of red blood cells that showed up in. Routine blood test. The cause was finally diagnosed as a secondary Polycythemia by the Hemotologist. The cat scam confirmed COPD. From there a plumanary lung function test. My body is producing these many red blood cells to get oxygen to my lungs. It's been a long journey. Now I see a respirologist every 3 months. He put me on ultibro inhaler which has helped my breathing. I still get very winded if walking to far or going upstairs. Tired as well so now on vitamin B-12 injections which makes me feel so much better.
