Irene. I can relate to your pseudo story. I can't do any oral antibiotics--allergic to them all now. I can no longer tolerate Tobramycin. I just finished 14 days IV Ceftazadime. Cough was gone before the end of the 14 days. Six days after PiCC line removed I'm coughing up some familiar sticky, yellow sputum. It's been seven years dealing with this and it is a struggle most days but I'm continuing to do what I can, when I can. Quality of life is my goal at this point. Having good support (my husband) makes a big difference. Blessing to all.
