Epidural Steroid Injection
An epidural steroid injection (ESI) delivers anti-inflammatory medication into the epidural space around your spinal nerves to relieve back, neck, or radiating leg and arm pain.
What it treats
ESIs are commonly used for pain caused by a herniated disc, spinal stenosis, or nerve-root irritation (sciatica). By reducing inflammation around the affected nerve, the injection can ease pain and improve your ability to move and take part in physical therapy.
What to expect
The procedure is performed by a physician using X-ray (fluoroscopic) guidance to place the medication precisely. It usually takes 15–30 minutes. You may feel brief pressure; most patients go home the same day. Relief can begin within a few days and may last weeks to months.
Safety & follow-up
ESIs are widely used and generally well tolerated. Your physician will review your history, medications, and any blood-thinners beforehand, and will discuss how many injections may be appropriate over time. We coordinate your care with your referring provider.
