Comparison of Two Lidocaine Administration Techniques
The objective of our study is to determine if technique of lidocaine administration can decrease pain perception.
Hypothesis: There will be a significant difference in pain perception between patients who are given lidocaine on the skin surface prior to subcutaneous injection and patients who are given only subcutaneous injection by standard approach.

|Primary Completion Date:||April 2015 (Final data collection date for primary outcome measure)|
|Experimental: lidocaine onto skin prior to lidocaine subcutaneous injection||
2ml 1% lidocaine placed onto surface of the skin immediately prior to 1% lidocaine subcutaneous injection
|Active Comparator: lidocaine subcutaneous injection alone||
1% lidocaine subcutaneous injection alone
This is a single center prospective, randomized, blinded study assessing pain perception following 2 different lidocaine administration techniques in subjects who have planned medical procedures requiring local injection of lidocaine. Subjects will be approached and consented to participate in the study. They will be interviewed after the scheduled medical procedure to assess their pain using validated pain scores. An investigator who is not present for the procedure and blinded to the randomization will gather data regarding perceptions of pain from the entire procedure.
