The purpose of this study is to evaluate if a paracervical block containing 1% lidocaine administered prior to IUD insertion reduces insertion pain. The hypothesis is that women receiving paracervical analgesia will experience less pain during IUD insertion than those who do not receive such analgesia.
Median Visual Analogue Score Measuring Pain [ Time Frame: 1) Speculum placement 2) Tenaculum placement 3) Paracervical block administration(if subject is in this arm) 4) IUD insertion 5) Five minutes post procedure ]
We asked participants to report their pain score on visual analogue scale (0mm=no pain and 100mm=worse pain possible) at the following time points:
