The lidocaine patch is currently only permitted for post herpetic neuralgia but the investigators want to study its effectiveness in post operative pain after inguinal herniorrhaphy
After open unilateral inguinal herniorrhaphy, patients are randomly divided into group L and group P groups. Group L attaches two lidocaine patches for 12 hours, above and below the incision site. Group P attaches two placebo patches for 12 hours, above and below the incision site. Pain scores are recorded for 30 minutes, 2 hours, 24 hours, and 1 week after surgery.
