@coffcoff I do have a nebulizer (DeVilbiss) and use it everyday with 0.9% saline. I have also tried it with acetylcysteine which is supposed to thin the mucus and after doing it everyday for almost a month, nada. I did see an ID doctor who put me on the 3 antibiotics 3 times a week. After 20 months the CT scan showed it was still there. He referred me to a pulmonologist in the Non-Tuberculosis clinic is a larger city, 1.5 hours away. I can't change to another pulmonologist as this is the only clinic in the province and it's very busy with patients. A different pulmonologist that I had done a "breath easy" zoom class told me that I might be one of those people that just doesn't produce much mucus. That may be true because when I was sick last year with something I was coughing up mucus and manage to get one sample, but one only. I have watched YouTube for huff coughing, and again, didn't help. I do and always have drank lots of water. I would like to be able to produce a sputum sample instead of having to rely on CT scans. The ID doctor went nuts with them. I had 7 scans done in 18 months. That's like 7000 x-rays. Not good. Oh, and I also have bronchiectasis, though the pulmonologist said it was serious, like 5%, and she wants to keep it that low.
