Hi, new to this group. My MAC was not symptomatic for many years, but recently I've had two episodes of coughing up frank blood and there is progression on the CT. My pulmonologist wants sputum as she thinks its time I should be treated. But I produce no sputum, have minimal dry cough. So I have Hypersal 7% and nebulizer. After first treatment, dry coughing but no sputum. Do I keep it up and hope something comes up? Has anyone else had this experience of disease of CT, but no sputum production. I'm a little worried about all the coughing because of the two episodes of hemoptysis where I just coughed up frank blood. She is talking bronchoscopy which I do not want because I have had tracheal surgery and am at high risk for tracheostomy with any intubation.
