Epidural Steroid Injection

Epidural Steroid Injection

An epidural steroid injection is performed to help reduce inflammation and pain associated with nerve root compression. Nerve roots can be compressed by a herniated disc, spinal stenosis and bone spurs, resulting in inflammation, pain, numbness, tingling or weakness along the course of the nerve. Epidural steroid injections help lessen the inflammation of the nerve root. The epidural space is located above the outer layer of the spine surrounding the spinal cord and nerve roots.

How is it performed?

  • The injection site is prepared and numbed. The doctor inserts the needle through the skin toward the spine.
  • Once the needle is in the proper space, a small amount of dye may be injected to verify the position of the needle with an X-ray.
  • After this, a mixture of numbing medication and steroids is injected in the epidural space.
  • The needle is then removed and the site is bandaged.
  • Following the procedure, the patient should rest for the remainder of the day and avoid driving for at least 12 hours after the injection.
  • It is normal to experience some mild drowsiness and numbness, tingling or weakness in the legs that day. The symptoms will gradually wear off.
