Yes, I have come to the conclusion that I must trust my doctor at NJH. You and I are the same.....my sputum culture showed Pseudomonas A also in September. Seven days of Levaquin did not work, although I felt better for about five days after finishing the Levaquin, then the green phlegm came back. By October, a follow up culture showed Pseudo once again. By November I changed my local pulmonologist for the Bronchiectasis clinic at NJH.
However, I was not told exactly what you were told.......that they don't treat Pseudo if you don't have symptoms. I could not wrap my mind around that, so at a follow up appointment, I pushed for treatment for my Pseudo. Had I known that they don't treat asymptomatic Pseudo, I never would have pushed as that would have put me in the hospital, my doctor said, for two weeks with inhalation therapy and monitoring......with no guarantee that the Pseudo would not come back.
It has been a process.
And, as you said, "not being a doctor myself", it is difficult to assess our health and what path to take.
