Transforaminal Epidural Steroid Injection in Castle Rock
What is a Transforaminal Epidural Steroid Injection?
A transforaminal epidural steroid injection (TFESI) is a minimally invasive procedure designed to relieve pain caused by inflammation or irritation of spinal nerves. This treatment involves injecting a steroid medication and a local anesthetic into the foramen, the opening where spinal nerves exit the spinal column. TFESI is particularly effective for conditions where nerve root inflammation leads to radiating pain, numbness, or weakness in the arms or legs.
How does a Transforaminal Epidural Steroid Injection Work?
The injected steroid reduces inflammation around the affected nerve, alleviating pain and discomfort. The local anesthetic provides temporary pain relief while the steroid takes effect over the following days. By decreasing nerve irritation, the injection can improve mobility and function, allowing patients to engage in physical therapy and other pain management strategies.
Because this is a targeted injection, the numbing medication can help confirm whether the treated nerve is the source of pain. The numbing effect typically lasts about two hours.
What Conditions are Treated with a Transforaminal Epidural Steroid Injection?
TFESI is commonly used to manage conditions such as:
Herniated or bulging discs
Spinal stenosis
Sciatica (lumbar radiculopathy)
Cervical radiculopathy (pinched nerves in the neck causing arm pain)
Nerve root compression from arthritis or bone spurs
Post-surgical nerve pain
Post-herpetic neuralgia (nerve pain following shingles)
How Should I Prepare for a Transforaminal Epidural Steroid Injection?
Before your procedure, inform Dr. Carrera’s team about any medications you are taking, especially blood thinners and antibiotics. You may need to temporarily stop blood thinners and nonsteroidal anti-inflammatory drugs (NSAIDs) such as Advil, Aleve, meloxicam, and naproxen.
If you are receiving IV sedation, you may be advised to avoid eating or drinking for several hours before the injection. IV sedation is rarely needed for this procedure.
Arrange for someone to drive you home after the procedure, as you may experience temporary numbness or weakness in the affected limb. Wear loose clothing to allow easy access to the injection site.
What Happens During a Transforaminal Epidural Steroid Injection?
Patient Positioning: You will lie on your stomach on a treatment table.
Local Anesthesia: A numbing agent may be applied to the skin to minimize discomfort.
Fluoroscopic Guidance: Using real-time X-ray (fluoroscopy), Dr. Carrera will carefully guide a thin needle to the targeted nerve root in the foramen.
Contrast Dye Injection: A contrast dye is injected to ensure accurate placement of the medication.
Steroid Injection: A mixture of steroid medication and local anesthetic is injected around the irritated nerve root.
Completion: The procedure typically takes 2–5 minutes.
How Painful is a Transforaminal Epidural Steroid Injection?
Most patients report mild to moderate discomfort during the procedure. The local anesthetic helps numb the area, but you may feel brief pressure or mild burning as the medication is injected. When performed by Dr. Carrera, patients typically rate the pain between 1 and 4 out of 10.
Dr. Carrera uses the smallest needles possible, even smaller than those used for flu shots, to minimize discomfort.
What Should I do After a Transforaminal Epidural Steroid Injection?
Avoid strenuous activities for 24 hours following the procedure.
You may gradually resume normal activities as tolerated, following Dr. Carrera’s recommendations.
Avoid submerging the injection site underwater for two days.
Do not apply a heating pad or ice pack directly to the area for the first 48 hours.
Mild soreness or temporary numbness in the leg or arm is common and typically resolves within a few days.
Dr. Carrera may have you fill out a pain diary to assess the effectiveness of the injection and guide further treatment.
When Will I Experience Pain Relief After a Transforaminal Epidural Steroid Injection?
Pain relief typically begins one day after the procedure, with full effects noticeable in one week. Some patients experience immediate pain relief due to the local anesthetic, though this is temporary.
How Often Can I Get a Transforaminal Epidural Steroid Injection?
You can usually repeat a transforaminal epidural steroid injection every three months, as long as you experience at least three months of at least 50% improvement in pain. It is recommended to limit steroid injections to five per year across your entire body to avoid potential steroid-related side effects.
How Long Does a Transforaminal Epidural Steroid Injection Provide Pain Relief?
The duration of pain relief varies among patients. Approximately 50–75% of patients experience at least a 50% reduction in pain lasting 3 months or longer. If sufficient pain relief is not achieved after two weeks, a repeat injection may be recommended, as the effects can be cumulative.
Are Transforaminal Epidural Steroid Injections Covered by Insurance?
Most insurance plans, including Medicare, Medicaid, and commercial insurers, cover transforaminal epidural steroid injections if the patient meets certain medical criteria. These criteria typically include experiencing pain for at least six weeks and failing conservative treatments such as physical therapy, medications, and lifestyle modifications. Some insurance companies allow for injections sooner than six weeks.
Insurance providers often require prior authorization before approving the procedure.
Who Can Perform a Transforaminal Epidural Steroid Injection Procedure?
Transforaminal epidural steroid injections should be performed by physicians with expertise in spinal procedures, typically interventional pain specialists or physical medicine and rehabilitation (PM&R) specialists.
Dr. Carrera is double-board certified in interventional pain medicine and PM&R, making him uniquely qualified to perform TFESI with precision and safety.
Dr. Carrera performs these injections in an in-office procedure suite, which helps patients save significant costs compared to a surgery center. Additionally, he uses exceptionally small needles, even smaller than those used for flu shots, to maximize patient comfort.
While some offices can take up to six weeks to schedule a transforaminal epidural steroid injection, Dr. Carrera’s team can typically perform the procedure within 2 to 7 days of your initial visit, ensuring timely pain relief.
Should I get a Transforaminal Epidural Steroid Injection?
If you are experiencing sciatica, chronic arm, leg, back, or neck pain, and are wondering if a transforaminal epidural steroid injection is the right treatment for you, a consultation with Dr. Carrera and his team can help determine your eligibility.
