Summary

This study looked at 39 people having lower back surgery for a herniated disc or spinal stenosis. Researchers checked for nerve pain before surgery and again 1, 3, 6, and 12 months after using a simple questionnaire. The goal was to see how common nerve pain is after surgery and how it changes over time.
