@pamelasc1 , just saw your post. If you have pseudomonas in your sinuses, one thing that works well is the steroid rinse: for one month, you rinse your sinuses with saline + small dose of steroid powder twice a day, then for the rest of the year you rinse with saline + small dose of steroid powder once a day. You should ask your ENT about it.For my lungs, I am intolerant to Levo, so I just nebulize with 3% saline twice a day, has been working so far.
Best wishes of great health!
