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.
Any patient of the Principal Investigator who has clinically diagnosed bilateral arthritis, tendinopathy, arthropathy, or compression neuropathy of the hand, wrist, or elbow where treatment with corticosteroid injection is indicated.
