@heathert It doesn't matter if you had mac or mai. Neither are curable; and the cause for getting it in the first place is either faulty genes, bronchiectasis, gerd, lung damage, or low immune system (low IGg), etc. Antibiotics do not erase those things. That is why mac re-occurrance is probable. That is why my dr wants me on 10 day a month antibiotics probably for life. We must all bear in mind, a negative sputem test does not neccessarly mean that it is gone, it means it is at an undetectable level. I am not saying my treatment is the way to go for everybody, but it is food for thought. (& mac-free since 2014, or at least undetectable level.)
