I had almost no pain with my right upper lung lobectomy until about a week later. Then I was in agony. It started at night and it took an incredible amount of time simply to sit up. I can't tell you exactly where the pain, it was so overwhelming.
Part of the cause may have been a tube that was inserted below the lung up to my shoulder. The purpose was to get rid of bubbles. Obviously the bubbles rose to my shoulder. But the only exit was below the lung. I'm sure there was a good reason even though the physics of it don't seem to add up. Anyway after loading me up with oxy on doctor's orders, a friend got me to the hospital. They took out the tube and I was fine. Of course, I was also pretty high by then.
I also had excessive drainage that the visiting nurses found very unusual, but at the time there was no pain. Just great difficulty in keeping up with the drainage. I don't know if that was a symptom/cause of the pain that followed after a week or not.
Not sure if this helps.
