I had a bout of aspirational pneumonia in May. My follow up chest X-ray on July 3rd showed still some consolidation in right upper lobe. The next X-ray on July 25 showed a little clearing but still persistent consolidation. I'm worried as to why this hasn't cleared up. Feeling well and 02 at 95% when running around all day. Report said could not rule out nodules. Is this possibly a mass or growth?
