@coffcoff I saw Dr Haas at NJH 1.5 years ago. Fortunately and ironically I may add, the most current scan I had in 10 years actually showed some improvement in my MAC right before I finally made it to Denver. (or at least no further damage), so the dreaded Foursome of drugs was not recommended. The big takeaway from my trip was “airway clearance.” However, I was told this would not really improve the disease, but was merely good “lung hygiene.” Im hearing otherwise in this thread, right? Anyway, I couldn’t do the daily regimen because I spotted blood, and hemoptsis was a big problem for me. My voice is very uneven for years now and I can’t sing anymore. I miss it terribly as it was part of my spiritual practice.
