9 Years ago I had surgery to remove a substernum goiter. Was on the table about five hours. Prior to that I hada bout withDVT. Several months after I suffered a collapsed lung spent ten days in hospital with a drain. The diagnosis was that part of the lung was damaged and would never return. I went the other day for a CT scan because they found nodules on my lungs Nothing big doind there but they say I have another Partially (same Lung) collapsed lung. Is that possible. Iquit smoking 9 Years ago.
