@pjas972j interesting theory! I was on a regime of levofloxacin and tobramycin for 30 days to try to clear pseudomonas. In addition, I was nebulizing with 3% saline and albuterol. During that time I was able to bring up a lot of mucus, all of which was bright lime green, and then turned to tan. But since I finished my antibiotic regime, I continued with nebulizing with the 3% saline and albuterol. Prior to that I was not nebulizing at all. I would just take a few puffs of my albuterol inhaler and then I would go put on my smart vest and do 220 minute Sessions and then do my lawn clearance and for the most part it worked pretty well. Now, doing the albuterol and saline nebulizing. I can’t get anything out whatsoever. I’m wondering if as your suggesting perhaps I have inflammation, which is stifling the removal of the mucus in my lungs. I thought perhaps she maybe everything‘s cleared out and I don’t have anything to bring up but after reading your post I’m thinking perhaps I’m delusional and everything stuck down there because of inflammation. I’ve gotta figure this out. Any suggestions?
