How a Transforaminal Lumbar Epidural Steroid Injection Works
A transforaminal lumbar epidural steroid injection (TFESI) is a precise, targeted treatment for lower back and radiating leg pain caused by nerve inflammation. This procedure delivers corticosteroids directly into the epidural space near the affected nerve root, reducing swelling and irritation. By addressing the source of pain at its origin, TFESI can provide longer-lasting relief than oral medications or physical therapy alone.
Patients with conditions such as herniated discs, spinal stenosis, or sciatica may benefit from this injection. The goal is to improve mobility and function while minimizing discomfort, allowing individuals to return to their daily activities with less pain.
What to Expect During and After the Procedure
The procedure is performed on an outpatient basis and usually takes about 30 minutes. A local anesthetic is applied to numb the injection site, and fluoroscopic (X-ray) guidance ensures precise placement of the medication near the affected nerve root.
Recovery and Results
- Mild soreness at the injection site may occur but usually resolves within a few days.
- Some patients experience immediate relief, while others notice improvement within a week.
- Pain relief can last several weeks to months, depending on the individual and their condition.
