@irenea8. The docs have never called my Pseudomonas "chronic." There have been periods over the last 5 years that sputum did not show it but it always returns. Currently I'm on Tobramycin twice a day. I neb two weeks on and two weeks off. I'm going to send my pulmonary doc a portal message and ask questions and hopefully get something back before my early AM iron infusion Wed. The iron infusion was ordered by my primary so the pulmonary doc is not aware. Thanks.
