Ann, I was diagnosed after a high-resolution CT scan a couple weeks ago. At my pulmonary doctor visit, I was given a TB test (which is negative) and next comes a bronchoscopy. He seems to think I will need the 3 antibiotics at this point. Came as quite a shock as I was having little to no symptoms, work out regularly, including aqua aerobics. Did have bilateral mastectomies 2-1/2 years ago, so don't know if any chest discomfort was from that or the bronch??
