@dantur I am sorry you are not finding good assistance where you are located. This support group can help - we are patients living with a similar diagnosis.

The treatment for mycobacteria infections (called MAC or NTM) take many months to eradicate the bacteria as it is hiding deep in the lungs. Do you see a lung specialist? They can add other treatments such as using a nebulizer and breathing techniques to get mucus out of your lungs. This can help make the antibiotic treatment more effective. Also, it is necessary to monitor, using sputum samples, to determine whether the amount of bacteria is decreasing, and then finally gone. If you have cavities, periodic x-rays or lung scans are needed to track your progress.
