Respiratory assessment

I am someone who gets crushed by respiratory viruses. My immune system seems better than average for avoiding GI bugs and UTIs but a small cold will leave me mildly short of breath for ages. I got COVID in Nepal Nov 2023 (I suspect I developed some minor PEs) and it took me over 6 months to recover. I’m currently recovering from a URI that started over a month ago.

I really want to chase this down in 2026 (I finally have descent insurance). Something like PFTs could quantify but probably not lead to specific treatments? Anyone deal with something similar — what tests or treatments helped you?

I’m a critical care nurse and was an endurance athlete prior to 2020 and have always felt like my respiratory system was never baseline as good as my peers.
