Spinal Corticosteroid Injection

(Spinal Steroid Injection; Epidural Steroid Injection)


A spinal corticosteroid injection is a needle injection in the back used to relieve pain or inflammation. Corticosteroids are injected into the epidural space around the spinal nerve roots of the cervical, thoracic, or lumbar portion of the spine, depending on the area that being treated.

Reasons for Procedure

The procedure is done to:

  • Reduce pain caused by swelling and irritation around the spine and nerve roots
  • Improve physical function for people with persistent low back pain with sciatica

Spinal injections are typically done when pain is not relieved by:

  • Rest
  • Ice and heat therapies
  • Medications
  • Physical therapy
  • Back exercises
  • Changes to the physical setup of the work environment
  • Changes to physical activities, including work
  • Spinal manipulation

Possible Complications

Problems from the procedure are rare, but all procedures have some risk. Your doctor will review potential problems, like:

  • Headache
  • Allergic reaction to the medication
  • Bleeding
  • Infection
  • Nerve damage
  • Fainting

Some factors that may increase the risk of complications include:

  • Current infection
  • Certain pre-existing medical conditions
  • Treatment with blood thinners or certain other medications
  • Poor health

What to Expect

Prior to Procedure

You may have the following done before the procedure:

  • A brief physical exam
  • Imaging studies to look for the location of possible causes of the pain, including:

Talk to your doctor about your medications. You may be asked to stop taking some medications up to one week before the procedure.


A local anesthetic and/or a sedative may be used. They may help to reduce pain and anxiety. You will be awake for the procedure.

Description of the Procedure

You will lie on your side on an x-ray table. The skin on your back will be washed with a sterile solution. A syringe containing corticosteroid medication and a local anesthetic will be injected through the skin and into a space near the spine. X-ray imaging will be used to guide the placement of the needle. Contrast material may also be injected to confirm that the needle is in the right place. The medication will be injected and the needle will be removed from your back. A small bandage may then be placed over the injection site.
