@regen99 recurrent pneumonia can be indicative of underlying MAC. That was me for years till my son in law ( an obgyn figured it out). Craziness! MAC takes a very long time to grow so results don’t typically come back for at least 8 weeks. GERD goes along with MAC pretty much too. I’m very sorry you are struggling so much. I hope your new care will be helpful. Sue is spot on about changing up the meds and adding a nebulizer. Nebulizing is probably the number one thing to do. It may be time consuming but my pulmonologist insists on it to bring that garbage up and out!! Prayers said for you. Irene5
