I was very surprised to see a forum for this affliction. Had MAC since 2019 but Dr decided to recognize it only recently after having a bronchoscopy. Looking back at all my CT Scans it was there all the while & why it was chosen to be overlooked is a mystery. I have COPD but was complaining of severe shortness of breath that my pulmonologist said wasn’t from my lungs must be heart (I get ct scans every 6mos, looking back at those reports all have MAC all over them) but I listened, went thru a wild goose chase with heart drs & other specialists to come back to my lungs. A broncoscopy was ordered and now Dr says this is what’s goin on. I dwell on that this wouldn’t be so bad if he didn’t overlook it from the start & why would he? I just got out of a short hospital stay for acute hypoxemic failure now have to breath with oxygen & soon my MAC treatments will start, I am scared to death! I’m scared of the side-effects. My hearing is the Only good thing I have left and I read that this can be affected by the antibiotics. I need to know what to expect so I can brace for it, can someone please answer truthfully what I have to look forward to especially in the beginning stages of treatment
