Chronic viral pneumonia for the last year as a result of COPD diagnosed in 2006. Was in pulmonary rehab for last 3 months and symptons went away. No more insurance so rehab stopped. Problems breathing again. Now say that I have emphysema. Several CAT scans over last year detected masses on my lungs in different locations that appear and then disappear. Doctor mystified. Think it might be time to get a second opinion.
