@gigiv I completely agree! I have been a daily jogger most of my adulthood but had cut back a two years ago for about 9 months prior to my problems. I often wonder if the jogging kept my lungs clear because after I stopped I developed mucus plugs, then pneumonia and finally a diagnosis of bronchiectasis. After I recovered from pneumonia I got back into jogging daily. It feels like an additional nebulizing treatment for me. I also do airway clearance breathing and have not had any issues for close to two years. Exercise if you can!
