First, your back will be cleaned with an antiseptic solution and a sterile drape will be placed. Next, the doctor will identify the area he or she will inject using an x-ray machine. Once the location is identified, you will feel a pinch and a burn as numbing medicine is injected into that spot using a fine needle. After the numbing medicine takes effect, you should only feel pressure as the doctor places an epidural needle into the correct position using multiple x-rays. Once the needle is in the epidural space, you may feel pressure or even worsening of your typical pain as the doctor injects the medication.
