An epidural steroid injection (ESI) is the delivery of powerful anti-inflammatory medicine directly into the space outside of the sac of fluid around your spinal cord. This area is called the epidural space.
ESI is not the same as epidural anesthesia given just before childbirth or certain types of surgery.
Spinal and epidural anesthesia are medicines that numb parts of your body to block pain. They are given through shots in or around the spine....Read Article Now Book Mark Article
ESI is done in a hospital or outpatient clinic. The procedure is done in the following way:
- You change into a gown.
- You then lie face down on an x-ray table with a pillow under your stomach. If this position causes pain, you either sit up or lie on your side in a curled position.
- The health care provider cleans the area of your back where the needle will be inserted. Medicine may be used to numb the area. You may be given medicine to help you relax.
- The doctor inserts a needle into your back. The doctor likely uses an x-ray machine that produces real-time images to help guide the needle to the correct spot in your lower back.
- A mixture of steroid and numbing medicine is injected into the area. This medicine decreases swelling and pressure on the larger nerves around your spine and helps relieve pain. The numbing medicine can also identify the painful nerve.
- You may feel some pressure during the injection. Most of the time, the procedure is not painful. It is important not to move during the procedure because the injection needs to be very precise.
- You are watched for 15 to 20 minutes after the injection before going home.
Why the Procedure Is Performed
Your doctor may recommend ESI if you have pain that spreads from the lower spine to the hips or down the leg. This pain is caused by pressure on a nerve as it leaves the spine, most often due to a bulging disk.
ESI is used only when your pain has not improved with medicines, physical therapy, or other nonsurgical treatments.
ESI is generally safe. Complications may include:
- Dizziness, headache, or feeling sick to your stomach. Most of the time these are mild.
- Nerve root damage with increased pain down your leg
- Infection in or around your spine (meningitis or abscess)
Meningitis is an infection of the membranes covering the brain and spinal cord. This covering is called the meninges.Read Article Now Book Mark Article
- Allergic reaction to the medicine used
- Bleeding around the spinal column (hematoma)
- Possible rare brain and nervous system problems
- Difficulty breathing if the injection is in your neck
Talk to your doctor about your risk for complications.
Having these injections too often may weaken the bones of your spine or nearby muscles. Receiving higher doses of the steroids in the injections may also cause these problems. Because of this, most doctors limit people to two or three injections per year.

Before the Procedure
Tell your provider:
- If you are pregnant or might be pregnant
- What medicines you are taking, including herbs, supplements, and other drugs you bought without a prescription
You may be told to temporarily stop taking blood thinners. This includes aspirin, ibuprofen (Advil, Motrin), clopidogrel (Plavix), warfarin (Coumadin, Jantoven), naproxen (Aleve, Naprosyn), and heparin.
After the Procedure
You may feel some discomfort in the area where the needle was inserted. This should last only a few hours.
You may be told to take it easy for the rest of the day.
Your pain may become worse for 2 to 3 days after the injection before it begins to improve. The steroid usually takes 2 to 3 days to work.
If you receive medicines to make you sleepy during the procedure, you must arrange for someone to drive you home.
ESI provides short-term pain relief in at least one half of the people who receive it. Symptoms may remain better for weeks to months, but rarely up to a year.
The procedure does not cure the cause of your back pain. You will need to continue back exercises and other treatments.
