  1. aPain score on an 11-point (0–10) numerical rating scale. (1) Pain score immediately after epidural procedure, (2) Pain score 14 days after epidural procedure, (3) Pain score 1 month after epidural procedure, (4) Pain score 3 months after epidural procedure, (5) Pain score 6 months after epidural procedure. Data were analyzed using the Bonferroni post-hoc test. P value < 0.01 was considered statistically significant
