@kathyhg and @suenfl My Pulmonologist went beyond getting defensive when I asked to consult an Infectious Disease specialist when my MAC treatment wasn't working - HE fired ME! Possibly one of the best things that has happened to me with this stupid disease - I now have a much better Pulmo who actually listens to me, backed off my meds, and prescribed 7% saline (original guy also said No to this.) If you don't feel comfortable with any physician, it's time to find a different one, and one well-versed in your condition.
Come back to the group with your location, you're almost sure to get a recommendation...Sue
