What Are Epidural Steroid Injections?
Epidural steroid injections (ESIs) are minimally invasive procedures used to relieve pain and inflammation in the spine. They deliver corticosteroid medication directly into the epidural space around the spinal nerves, targeting the source of irritation and reducing swelling that contributes to pain. ESIs are commonly used for conditions affecting the lower back, neck, and radiating nerve pain (sciatica).
When Are Epidural Steroid Injections Recommended?
Epidural steroid injections may be recommended for patients experiencing:
- Herniated or bulging discs
- Spinal stenosis (narrowing of the spinal canal)
- Sciatica or nerve root irritation
- Degenerative disc disease
- Chronic low back or neck pain that hasn’t improved with conservative care
How Are Epidural Steroid Injections Performed?
The procedure is typically done in an outpatient setting under local anesthesia and fluoroscopic (X-ray) guidance. After cleaning the skin, the physician inserts a thin needle into the epidural space and injects a mixture of corticosteroid and anesthetic. The process usually takes 15–30 minutes, and patients can return home the same day.
What to Expect During Recovery After an Epidural Steroid Injection
Mild soreness at the injection site is common for a day or two. Pain relief may begin within a few days and can last from several weeks to months. Patients are advised to rest the day of the procedure and resume normal activity the following day unless otherwise directed.
What Are the Risks of Epidural Steroid Injections?
Although rare, potential risks include:
- Temporary increase in pain or headache
- Infection or bleeding at the injection site
- Nerve irritation or injury
- Allergic reaction
What Are the Benefits of Epidural Steroid Injections?
ESIs can provide:
- Significant reduction in inflammation and pain
- Improved mobility and function
- Faster return to daily activities
- Delay or avoidance of surgical intervention
