Otter2154, the only difference in our symptoms is that I do not produce phlegm.

Sure. Pulmo put me on Symbicort (2 puffs, twice daily), and Singulair (one pill before bed). Additionally, I’ve been doing my own deep breathing exercises with a 40lb. resistance band ... plus lots of stretching ... these have helped me greatly. And I’ve been riding my bike and getting much general exercise. As the moderator also mentioned, I’m not ruling out having had a bad run with Covid back in Nov/Dec that has resulted in some slow-to-heal lung damage. I was miserable back then; SOB, soaking night sweats, the coughing, debilitating fatigue, horrible tinnitus ... I could barely do anything! Every day though, things seemingly and slowly get better. I’d say I’m 85-90% back to being myself, save for this lingering vicious phlegm issue. I’m a fit, healthy 56 y/o male who has never experienced anything like this before.
