@irene5 You are right. It was an xray that alerted my primary's partner that something was there, followed by a CT that confirmed bronchiectasis and "suspected MAC" which was confirmed by sputum culture. It was severe enough that the pulmonologist started treatment while waiting for sensitivity tests to come back, which confirmed his choice. It was also a repeat CT that showed enough improvement to quit the meds and go with just 7% saline to keep the remaining infection under control. Like @unicorn my body became more and more unhappy with the meds over time, especially after 6 months of every day!
