Vibratory Anesthesia in Trigger Finger Injections

Summary

This study aims to compare the effectiveness of the use of no topical anesthesia, topical coolant, and the use of vibration in the reduction of pain during trigger finger injections. This will be done by randomizing patients who are diagnosed with trigger finger, warrant and choose to continue with a steroid injection into each of the respective anesthetic (or lack thereof) methods described. After conducting this and gathering data on the subjects pain felt, we will compare the analgesia from each of the anesthetic methods.
