Table 1 Comparison between patients with and without compressing disk intervention during the intradermal lidocaine injection. Values are expressed as mean (standard deviation), median (interquartile range), or proportion. VAS scores were significantly higher in no compressing disk compared to the intervention group, anxiety Likert scores, pulse rate and patient satisfactory Likert scores were no significantly different
