So I saw the pulmonary doctor today for the first time. We reviewed my CT scan. My oxygen level was 97%. There was a small spot in the scan. I'm going for my PFT test tomorrow to determine if it is just potentially scarring/a spot/emphysema.  I wasn't sure what to expect with the test, how long it takes, and what "normal" results might be. Any guidance and positive thoughts that it is nothing would be greatly appreciated. I have been a nervous wreck since this all began in April. I appreciate all the support I have found on here.
