If you are having it performed and desire IV sedation they will require you to not eat 8 hours prior to the procedure and only clear liquids up to 4 hours prior. Nothing to eat or drink for the last 4 hours prior. If you are not receiving sedation just don’t eat or drink 2 hours prior please. You will be monitored closely with blood pressure, and blood oxygen monitoring device. Local anesthetic and freezing spray will be used before the actual injection to diminish any discomfort. The physician then locates, under fluoroscopy (X-ray), a specific anatomical target site or location that is near the problem area. Contrast is used to confirm proper placement of medication, typically anesthetic and steroid, is then injected. The Procedure may cause some slight discomfort, however is typically not painful.
