This procedure is administered to relieve pain and inflammation from irritated spinal nerves. It only takes a few minutes to administer the steroid-anesthetic medication to clear away lower back and leg pain. The process begins with the patient laying face down with a cushion directly under the abdomen to bend the spine and open up the foramina. The physician will then inject a local anesthetic to numb the skin and tissue around the spine and will guide a needle to the space around the irritated nerve root. A contrast solution is used to determine the correct point for injection and the medication will be administered to the spinal nerves. Once the steroid anesthetic sooths the irritated nerve roots the patient should feel relief right away. Some patients may need more than one injection in order to receive the full relieving effects of the medication administered.
