Stage 1b lung cancer

My journey started March 26, 2020 when a lung biopsy showed cancer in the lower left lobe. A PET. scan showed the cancer was no where else. I had surgery May 11 to remove the left lower lobe. I was feeling really good but a month later I started coughing uncontrollably. Dr put me on antibiotics and prednisone twuce. Still no better. I took 4 rounds of chemo which wasn't bad. However; the shot to build my immune system up was horrible. After each hemo followed by the shot, my bones ached all over. I took my last chemo Sept. 7. I go tomorrow,  Sept. 29 for a PET Scan. The one in July showed some uptick and I had another biopsy close to the area of concern and it showed no cancer. I've fractured a rib and pulled a muscle from coughing so violently. Still don't feel any better. Praying things go well and this is just part of the healing process. Not sure if anyone else has experienced this but if so, I would love to hear any feedback. Blessings to all.
