  Purpose

The purpose of this study is to provide preliminary data for a Program Project Grant to the National Institutes of Health to examine specific explanations regarding identifying patients at risk for chronic pain after surgery and identifying mechanisms which may be altered to decrease this risk.

This study will help investigators better understand chronic pain that develops after surgery. We are proposing to study different factors related to the surgical experience and factors in the environment to determine if any play a role in the development of chronic pain after surgery.
