An epidural steroid injection (ESI) is a minimally invasive procedure that can help relieve neck, arm, back, and leg pain caused by inflamed spinal nerves. ESIs may be performed to relieve pain caused by spinal stenosis, spondylolysis, or disc herniation.

During the procedure the patient lies face down on the procedure table, a pillow may be put under the stomach area for comfort. Local anesthetic is used to numb the skin and tissue down to the vertebra. The Physician will use image guided x-ray to ensure the correct placement of the needle tip. The Physician will then inject a contrast solution to confirm placement of the needle. Then a mixture of anesthetic and steroids is injected to reduce the pain and inflammation. The needle is removed and a band aid is used to cover the tiny wound.
