The cervical spine is the part of the spine located in your neck. The spinal cord sits inside a tunnel created by the vertebrae (bones making up the spine). It is also protected by a soft layer of tissue called the dura. The epidural space is the area between the bony canal and the dura layer of the spinal cord.
An epidural injection is a procedure to deliver medication into this epidural space. The medication may include an anesthetic that will numb the pain and a steroid that can decrease swelling and irritation.

An epidural injection may be done if you have pain in your neck and upper limb that is not responding to conservative treatment, such as oral medications and physical therapy.
Damage to local joints or discs of the spine can irritate the nerves exiting the spinal cord. This can cause inflammation around the nerves, which leads to pain. The pain may be in the neck or may travel down to the shoulders and arms, and even to the hands and fingers.
The injection may provide relief for a few weeks or even a couple months depending on the exact cause of pain.
This procedure may help manage the pain until the injury that caused the nerve irritation has time to heal.
Problems from the procedure are rare, but all procedures have some risk. Your doctor will review potential problems, like:
If you smoke, talk to your doctor about ways to quit. Smoking can weaken your immune system and slow healing.
Your doctor may not want to do this injection if you have:
Your doctor may begin with conservative treatment, such as rest, medication, physical therapy, and exercise.
Before the procedure you may need:
In addition, talk to your doctor about your medications. You may have to stop taking some medications up to one week or more before the procedure.
Additional considerations include:
You will be awake during this procedure. A local anesthetic will be used to numb the skin before the injection. Your doctor may also give you medication to help you relax.
You may have devices attached to help monitor your blood pressure, heart, and oxygen levels. You will be asked to lie on your stomach or side on an x-ray table or sit in a chair. The skin around the injection site will be cleansed. A local anesthetic will be given to numb the area.
The doctor will inject a contrast dye. This dye will help highlight the area to guide the needle. This is done using a type of x-ray called fluoroscopy. Next, when the doctor has reached the epidural space, the steroid will be delivered.
A small bandage will be placed over the injection site. You may be able to go home after being observed.
The injection only takes a few minutes. The entire procedure may be 30-60 minutes.
There is local discomfort as the numbing medication first goes in. But the rest of the procedure should not be painful. Once the injected anesthetic wears off, you may have some discomfort.
Your doctor will assess your level of pain relief.
You will have to reduce your activity level for the first day or so. You can apply ice to the affected area to relieve swelling and discomfort. Pain can be managed with medications. Proper care of the insertion site can help prevent infection. You can slowly increase your activity as tolerated or by your doctor's instructions, but injected steroids may take time to work. If you have diabetes, monitor your blood sugar levels more carefully a few weeks after an injection. The medication that was injected may cause elevated blood sugar levels.
Call your doctor if any of these occur:
If you think you have an emergency, call for emergency medical services right away.
