Oh Miriam, I know how frustrated you must feel. Yes, sometimes the treatment doesn't eliminate the infection - as in my case and possibly yours as well. But lowering the infection is sometimes enough - I have managed to stay off the meds for 4 years now with airway clearance, exercise and a good diet. Also by keeping my asthma well controlled & avoiding respiratory bugs.
It will be interesting to hear what the doctor has to say. After the second post-treatment but still-positive culture, my doc has decided as long as my bronchiectasis remains stable and I don't feel sick, we just wait.
Do you feel healthy (other than the aftereffects of the meds)? And is your cough gone?
Will you let me know what your doctor advises?

My doctors did not expect improvement in the CT with treatment but hopefully no worsening. My cultures have been free of MAC for two years but CT no better
Have you had recent cultures? This always seems a more reliable indicator of active disease, at least for me as I never had symptoms
