For the past couple of weeks I’ve been having some weird breathing. It feels like I can’t breathe, seriously, like it’s a hard chore to breathe in. And it’s happening ALL day, I don’t notice it once I wake up, but as soon as I get out of bed it starts. I went on a walk today, and that was really the only time I didn’t notice it. I’m just confused I guess. My blood oxygen is at 99% all day, my heart rate is okay. I feel fine other than not being able to breathe. Has anyone ever experienced this?
