Your Injection Procedure
A lumbar epidural injection is an outpatient procedure. It’s often done in a hospital or an outpatient surgery center. Before your injection, your doctor will ask you questions about your health. He or she also will discuss how you need to prepare.
Diagnosing the Problem
A BLOCK is a special test. It helps your doctor find the cause of your symptoms. During the test, medications is injected near your spine. This “blocks” the sympathetic nerves in that region. If these nerves are causing your problem, the injection will relieve your symptoms for a while.
The Cervical Epidural Injection
To help relieve your pain, mediation is injected into the epidural space. This space surrounds the dura within the spinal canal. Your doctor may also do a nerve block. During the procedure, medication is injected near a specific nerve root (the part of the nerve that leaves the spinal canal). For certain types of neck pain, your doctor may suggest cervical epidural injection with the treatment, medication is injected to help the doctor find the source of the pain. It can help relieve your pain and soreness.
Your doctor may have suggested you have a lumbar epidural injection. This procedure can help relieve low back and leg pain by reducing inflammation (swelling and irritation). Also, an injection can help your doctor diagnose the source of your pain by numbering certain areas of your back. Where you are injected depends on the goal of the injection.
Epidural Steroid Injections
General Information: These are injections of steroids (cortisone medicines) into the space just outside the covering (the dura) of the spinal cord. Because the injection is outside (epi) the dura, it is called an epidural injection. This procedure has nothing to do with spinal anesthesia used for operations.
The spinal cord travels from the brain to the waist in a tunnel in the back part of the spine. About every inch along the way, the spinal cord gives off branches to the right and left. These branches carry sensations from the brain to various part of the body to make move. Also these branches send back variety of sensations (e.g., pain) through the cord and then to the brain.
These injections are performed when it is thought that inflammations is part of the process that causes the pain. A steroid medicine, which is a very potent anti inflammatory drugs, works best when it is injected into the area where the inflammation is occurring. Because the nerves of the spinal cord pass through the epidural space, the medicine comes in contact with them.
