This has been going on for quite a while now, it’s like I need to keep taking deep breaths every minute… my chest feels a little packed and I feel very little oxygen, though I do breath just fine. I had Covid around 2 or 3 months ago and somehow I feel it got even worse after that. I don’t know if it’s all in my head or if I actually had my lungs damaged. I’m also a smoker, which makes me feel even worse. I’m currently swimming and trying to quit smoking completely.
