I'm just home from hospital, after a week on iv antibiotics for atelactasis and lung infection. I'm still on oral antibiotics (Augmentin), but just wondering when I should start feeling better. I have a paralyzed hemidiaphragm (from previous heart surgery) , which generally effects my lung capacity , and I know infection is not helping those symptoms. Anyone have any experience of atelectasis, and how long before I should get my energy back?
