The goal of this research study is to learn more about how different uses of a numbing medication might affect pain levels while getting an IUD placed. The investigators are also studying patients' opinions of their clinicians' empathy.
The investigators are inviting patients who have never given birth who arrive at their clinic visit seeking an IUD.
Usually, at University of California, San Diego (UCSD), for patients who have never delivered, clinicians numb both the sides of the cervix with a lidocaine-based paracervical block. The purpose of this research study is to compare perceptions of pain between buffered (2 cc of sodium bicarbonate, 18 cc of 1% lidocaine) vs. unbuffered paracervical block (20 cc 1% lidocaine) during IUD placement for nulliparous women.
