I am 69 and have always been healthy & very active other than Crohn's which is under control w Humira (Crohn's & bronchiectasis are associated, not clear why). Was dx incidentally w BE 2012, "idiopathic", stable & asymptomatic til I started having chronic dry cough & ended up eventually w BE/NTM specialists who did all baseline blood work you are probably getting & then positive for MAC. Someone here said "we run away from our dx" & I recognized that! I am treating in a study but still have to deal w "fight or flight" re health issues. Luckily my condition is mild but the fatigue is challenging!
