I haven’t experienced a “tight throat” although I do experience frequent swelling with my tonsils which I probably should have had removed when I was younger. I agree in terms of this not being isolated to the lungs. I feel like mine is either anxiety, stress induced or silent reflux. Honestly maybe a mixture of all of those but I’m really just not sure how it randomly started. I am curious if post COVID has anything to do with it?

I do feel short of breath when exercises but I actually feel it’s gets better for me following the workout because I almost feel like working out forced my brain to breath deeper if that makes sense
