@jweisser Thanks for the update. I would urge you not to be afraid of the tests. You want to know for sure what's going on in your body so you can get the best care, to maintain the highest quality of life, no matter what. The PFT will yield good information. For me the definitive test that provided the basis for a solid diagnosis was the CT scan. Ask the pulmonologist how many cases of bronchiectasis he/she has treated. Some pulmonologists are very inexperienced when it comes to bronchiectasis. You need someone who is up on research and treatment. Please keep us informed. I join others in the forum in sending best wishes and hugs.
