I posted my PFT follow up results here a short while ago. This was done after a flare I had in October. While all the numbers remained the same as last one in 2019, even a little better, I don't feel the same physically. I noticed that my IC is slightly low buth within normal limits, but my FEF 25-75% is extremely low, indicating small airway disease? Idk, I felt perfectly fine and physically capable until extreme stress brought on flare, just trying to make sense of it all
