Bilateral Arthritis of Wrist

This research study aims to evaluate injectional pain at the site of needle insertion for corticosteroid injections (CSI) of the upper extremity depending on different modes of anesthetics. Each individual's perception of pain upon receiving a CSI with two out of three modes of anesthesia (control/no anesthesia, vibrational anesthesia, vapo-coolant anesthesia) will be utilized to compare these variables and determine the method that is associated with the least pain.
