@ginak Hi Gina! How much blood did you cough up? I've had 2-3 TBS blood coughs twice, but I felt fine otherwise, and nothing ever came of it, other than that it was scary. I don't take any antibiotics, but recently started nebulizing 7%, based on what I've learned here. The more I hear of it, the more I think coughing up blood is just an annoying part of having brochiectasis/MAC, even when we have no other symptoms. Good luck! Lori
