In the simplest of terms, an epidural corticosteroid (steroid) injection is a way to deliver pain medicine quickly into the body with a syringe.
The medicine is injected into the epidural area. This is a fat-filled area that covers the spinal cord to protect it and the surrounding nerves from damage.
Sometimes pain relief is short term. Other times the benefits continue for some time.
If you have intense, difficult-to-treat pain in your legs or arms from inflamed spinal nerves, then an epidural steroid injection might give you quick relief. Often, nerve passages from the spine to your arms or legs become narrowed, causing this pain. This narrowing can cause inflammation of the spinal nerves.
A number of conditions may add to this narrowing, including:
Injected steroids reduce inflammation and opens up these passages to provides pain relief.

Once the procedure is done, you can return home. Usually, you'll be able to return to normal activities on the next day. The steroids usually begin working within 1 to 3 days. In some cases, you might need up to a week to feel the benefits.
Many people get several months of improvement of pain and function from the injections. If the injection is effective, it can be repeated. If you have any side effects, be sure to contact your healthcare provider.
If you don't have pain relief, talk with your healthcare provider. This may be a sign that the pain is coming from some place other than the spinal nerves.
