Brief Summary
Injections that freeze neck joints can be done using x-rays or ultrasound imaging, which as a newer way of guiding the needle to the right spot. This study will look at how often freezing liquid goes into a blood vessel during neck injections that freeze neck joints when ultrasound guidance is used to place the needle. When this happens, it can go undetected because it does not make the patient feel any different, however it could cause a test block to be falsely negative, leading to the wrong diagnosis. Based on previous studies, we think that this happens rarely, and the purpose of this study is to prove that conclusively
