Transforaminal Epidural Steroid Injection
Compression of spinal nerves caused by spinal stenosis or disc herniation can result in significant pain. Transforaminal epidural steroid injections (TFESI) and lumbar epidural steroid injections (LESI) can drastically help relieve the pain in the lower back and legs caused by spinal nerve issues, with peak relief being felt after anywhere from 36-48 hours following the procedure.
Before the Procedure
- Do not eat for six hours before the procedure, although you may drink clear liquids up to two hours before the procedure.
- Take your regular medications with a small sip of water.
- Arrive 30 minutes before your procedure.
- You must bring a driver to take you home.
- Do not take aspirin seven days prior to your procedure, and avoid taking NSAIDs three days prior to your procedure. Please inform us if you are taking any blood thinners.
- Wear loose, comfortable clothing.
During the Procedure
You will be asked to lie on your stomach on a table with a pillow placed under your abdomen. The injection site is prepped and numbed with medication.
The injection is performed between the posterior spinal column in the lower back at the location where your pain originates. A small needle is inserted at the location and advanced to the epidural space using a live X-ray (fluoroscopy) machine to ensure proper needle placement, followed by an injection of contrast dye to confirm location. A steroid and lidocaine are then injected together to bathe the structures that are inflamed and decrease pain.
The procedure takes approximately 15-30 minutes.
After the Procedure
The area served by the nerve in your lower extremities may be numb for several hours after the procedure from the anesthetic agent injected around the nerve. Our clinical team will provide you with discharge instructions afterward. The steroid will begin to work 36-48 hours after the procedure, and injections may be repeated in 1-2 weeks.
