I was diagnosed with emphysema years ago. I was taking 2 puffs of generic Spiriva every day. All was good till I got covid. I'm not vaxxed, got covid in January of this year. After I got over it, I had a lot of problems. Breathing was worse and the inhaler wasn't making it better. My oxygen was around 92-94. I had humming in my ears non stop. Coughed constantly. Heart palpitations. A constant back pain in the same spot (thought I had lung cancer). Fatigue. Just in general felt like crap. I quit using the inhaler and everything stopped. Oxygen stays around 97-98 and heart rate went back to normal. No more ear humming, fatigue and back pain went away. Than I started only using 1 puff a day cause I didn't know if quitting it completely would do more harm than good. I ordered generic advair and just started using it. Has anyone that got covid experienced anything like this? It is crazy.
