Summary
The purpose of this study is to determine if creation of a skin wheel with bacteriostatic normal saline, which includes 0.9% benzyl alcohol, is less painful and provides a similar level of anesthesia compared to 1% lidocaine. Participants will receive both types of anesthesia, in random order.
