Thank you Lisa. I spent about 45 minutes yesterday with my Pulmonary PHP. She's the one I see most often. She took more time with me than she normally does and did her best to answer a lot of my questions. When she took my blood oxygen level while I was sitting down, my O2 was 99 and my pulse was 68. She then said let's go for a walk with the oxygen sensor still attached and she had something plugged into it that she held. We didn't walk for more than 5 minutes and I'm guessing about 50 or 60 steps. As we were walking my O2 reading dropped to 88 and my pulse went up to the 90's. She Acknowledged that I had a whole lot of mucus plugs in my lungs and they were interfering with my airway, especially upon exertion. She prescribed Augmentin 875 and a 3% salt solution for my nebulizer, as well as a "puffer" for me to exhale into, that 's supposed to break up the Mucus. No results from the left node. It was too small. She stated there is no evidence of malignancy, and they're going to follow me closely over the next few months. So, at least for now, I'm very happy no cancer was found.
Thank you Lisa @lls8000
