When I was diagnosed with NTM and bronchiectasis about 7 months ago the doctors asked me to have several tests which I did. I also researched for hours for a good doctor. I found one of the best in this field. She is about an hour from me which is no big deal. She also works with an infectious disease doctor who I very happy with.
Research in your area for a doctor that specialized in just your disease. They are out there you just need to find one.
Good luck! I am not on the antibiotic regimen yet. I am looking into alternatives. I do not want to put all the chemicals in my body.
