Alice when I was just in the hospital they said some of my tests were suggestive of Pulmonary Fibrosis. The pulmonary doc wanted to do a CT scan but the hospitalist didn't think it was needed. When I looked it up online, some of the symptoms it listed were certainly familiar to me. I have a follow up coming up with my pulmonologist; so I may bring it up to him. I didn't know that about exhaling. Thanks.
