For years I had this. I would get antibiotics. Get better and it would come back. Finally a young intern sent me for a scope were they take a sample in your lungs. They grew that and found mac. Then i had a ct scan and we could see the two spots. I get one every year and nothing has gotten worse. Sputum never shows a thing because I am anti biotics all the time. Not sure what will happen when arithromycin doesn't work. I did do the big three when they first found it.
Problem I found was by the time u get to see someone and get on somthing and it doesn't work and u go back. It has really go ahold. It has gotten worse over the years or the drug is less effective . We are what we eat. My body ph is on the acidic site. That is not good. I have been working to get it alkline but the antibiotics keep it acidic. Drs are fixing the problem after we have made the problem by eating bad food. Sugar ,dairy and meat are all acid forming. Our body is smart it does everthing it can to stay alive but we keep feeding it junk. I will beat this mac and get off the antibiotics. If u are intrest read Dr Robert Morse N.D. book The Detox Miracle Source Book on amazon. It is very informative and so true. Garry
