- Average Pain Score at Rest [ Time Frame: 48 hours ]Pain scores every 4 hours for 48 hours postoperatively, utilizing the numeric rating scale with 0 being no pain and 10 the most severe pain you can imagine.
- Average Pain Score With Coughing the First Morning Following Surgery [ Time Frame: First morning following surgery ]Patients were asked on the first morning following surgery how they rated their pain with coughing utilizing the Numeric Rating Scale for pain, with 0 being no pain and 10 being the worst pain imaginable. The range is 0-10.
- Average Pain Score With Coughing on Second Morning After Surgery [ Time Frame: Second morning after surgery ]Numeric rating scale pain score with coughing on second morning after surgery, range 0-10.

- Number of Participants With Pain at Thoracotomy Site 3 Months Postoperatively [ Time Frame: 3 months postoperatively ]Patients were contacted at 3 months post-thoracotomy and asked if they had pain at the thoracotomy site. We observed the number of participants with the presence of pain at thoracotomy site at 3 months postoperatively.
