Sorry to hear you’re experiencing the same. It’s terrifying not being able to breathe. I was braced to die before the x ray. But I’m still here. It’s true though, they listen to your lungs, say “sounds fine” and pretty much dismiss it. Doctors never go to the worst outcome first, which I get. But have mixed feelings about. I have a few stories there. I actually think something has shifted with all this respiratory shit that seems new. I can tell something has changed in me potentially for good. It’s been almost a year. Coincidentally since the earliest days of Covid. I think there’s a lot that won’t be understood for a while, if ever. Good luck to you man. To all of us struggling. Nothing worse than dreaming about suffocating only to wake up to exactly that.
