I'm so sorry "Payette". I too feel totally blindsided and I'm losing confidence in my pulmonary and worried about my local ID doctor who suggested 3 meds one being Tetracycline. She also said she would like to talk to doctors at NJH. I've read the Mycobacterium Abscessus is highly resistant to Tetracycline-which is why I'm worried. I won't get into NJH until May 20-30. They are testing my sputum but Banner already has as well. My strain (or substrain?) has the active erm gene (spelling?), so no macrolides. I also have one cavity but would not be surprised if I have 2 or more by now. I'm with you, I was really surprised about the 8 week clearing. I just need a doctor that is sure about which treatment I should start. I wish everyone the best.
