When reading in this site I see that people with pseudomonas in the lungs use Tobi or whatever else for this. My daughter 2 has pseudomonas but not on anything for this. I was told that it is a very low when cultured for. My question is, if she does have a very small amount in the lungs should she be getting treatment for this or is usually when it starts to effect the lungs????? Has been on antibotics to help fight it. Is this a growth that comes and goes, can it be mild or sever, and can the antibotic help fight it enough to keep from getting worse?????Very confused on this one.
