Overview
A lumbar transforaminal epidural steroid injection (TFESI) is a minimally invasive procedure used to treat lower back and leg pain resulting from irritation or compression of spinal nerve roots. Unlike traditional epidural injections, TFESI delivers medication more precisely to the affected nerve as it exits the spinal column, offering targeted relief.
This procedure is often used when symptoms are caused by herniated discs, foraminal stenosis, or nerve root inflammation.
Conditions commonly treated with TFESI include:
- Lumbar radiculopathy (sciatica)
- Foraminal disc herniation
- Foraminal stenosis
- Nerve root inflammation from workplace or auto injury

What are the risks and side effects?
Risks and side effects are minimal, and serious complications are rare. We take every precaution to ensure your safety. Potential risks may include but are not limited to:

Ask your provider if you have any concerns. Your physician will review the risks in detail before the procedure to ensure you are fully informed.
