Toni, I hope this is easily resolved. It sounds like you are in the thick of it, and it's always a bit alarming to hear of a new bug revealed in the cultures.
Sue, your research and sharing is always amazing, and so appreciated.

My last sputum culture (late October), came back negative for MAC again (thank you chlofazamine trial and airway clearance!) but did show Gordonia Otitidis. Dr. Winthrop said it was not a concern, "usually due to an environmental contaminant." But around Thanksgiving I began having sinus issues, starting with a one-sided headache that hurt when I coughed. I have not gotten really sick, just stuffiness and drainage, that is especially annoying when, at night, it combines with the stuff coming up from my lungs. I've been managing, more or less, with saline nasal washes and flunisolide nasal drops, but now I'm wondering if the contaminant in my sputum might be from my sinuses. I have an appointment with Dr. W next week and will ask him. It would certainly be nice to clear my head!
All best to all of us.
