Clint, I just went through the exact thing you are going through. In Nov. had ct/pet scan done, and it showed a spot on my upper lung. Went to a thoracic doc who put me on antibiotics for 10 days, also told me to take Mucinex to help break up anything in there. I just had my ct scan done on the second of this month and the spot is gone. What a relief!! So I'm praying that you will have the same result. Take care.
