Ive had several spirometry tests, bronchal provocation tests, CT scans, xrays, all seems fine and within normal limits. but getting puffed say just picking shit up off the floor. Can ride the bike fine, unless its steep up hill. Gotta walk that, and that kills me. Have lots of phlegm but its so sticky, it doesnt want to come up easily at all. Cough is dry, heavy cardio irritates it. Been on preventors, ventolin, ranges of pills including prednisolone (had to stop that as it reduces immune system effectiveness), mucolytics and expectorants, nothing really seemingly helping.
all the bad stuff has been ruled out, no bronchitis, cancer, emphysema, asthma etc.
Next steps are a bronchoscopy and the idea of that is really uncomfortable.
Im at the point im wondering whether i may have had covid at some point unknowingly and gotten some sort of lasting damage. Would have thought that would have showed up on some of the battery of tests to date.
The breathlessness could be heart related, but it doesnt explain all the other respiratory symptoms. Really annoying me.
