Cervical Epidural Steroid Injection (Cervical ESI)
If you are living with neck pain that radiates down the arm — and it has persisted despite medication and physiotherapy — a Cervical Epidural Steroid Injection (Cervical ESI) may be the targeted, non-surgical treatment that finally provides the relief you have been looking for.
Understanding Cervical Radicular Pain
Cervical radicular pain — commonly described as neck pain that shoots, burns, or travels down the arm — occurs when one or more of the nerve roots exiting the cervical spine become compressed or irritated. The two most common underlying causes are:
Both conditions produce a characteristic pattern of symptoms that is important to recognise.
Warning Signs to Watch For
- Neck pain radiating into the arm — pain that begins in the neck and travels into the shoulder, upper arm, forearm, or hand; often described as sharp, shooting, or intermittent electric shock-like sensations along the arm
- Numbness, tingling, or weakness — a pins-and-needles sensation or loss of normal feeling in the arm or hand; in some patients, the muscles of the arm or hand may become noticeably weak, affecting grip strength or fine motor tasks
If you are experiencing either of these symptoms — particularly if they extend below the elbow or into the fingers — a cervical spine assessment is warranted.
What Is a Cervical ESI?
Cervical ESI is a minimally invasive, non-surgical procedure in which a mixture of local anaesthetic and corticosteroid is injected directly into the cervical epidural space — the area surrounding the spinal cord and nerve roots within the neck.
By delivering the medication directly to the site of nerve root irritation and compression, the procedure reduces inflammation and swelling around the affected nerve root, providing targeted pain relief and improving neck mobility — without the risks and recovery time associated with surgery.
Who Is Cervical ESI Suitable For?
Cervical ESI is indicated for patients with:
การทำ Cervical ESI เหมาะสำหรับผู้ที่มีอาการดังต่อไปนี้ :
- Cervical disc herniation with nerve root compression confirmed on imaging
- Cervical spinal stenosis causing radicular symptoms in the arm
Patients who have not achieved adequate relief with oral medication or physiotherapy are appropriate candidates for this procedure.
Important: A Cervical Spine MRI is required before proceeding with Cervical ESI. The imaging allows the physician to identify the specific level and nature of nerve root compression, plan the injection approach precisely, and confirm that the patient's symptoms are consistent with the imaging findings.
The Procedure (Approximately 15–20 Minutes)
This is a safe, minimally invasive outpatient procedure. General anaesthesia is not required. Patients remain awake throughout and receive local anaesthetic only.
- The patient lies face down on the procedure table; local anaesthetic is applied to the skin at the injection site to minimise discomfort
- The physician uses real-time fluoroscopy (live X-ray) combined with contrast dye to precisely identify and confirm the position of the cervical epidural space and the target nerve root level before any medication is delivered
- The corticosteroid and local anaesthetic mixture is injected into the epidural space at the affected level; patients typically experience only mild pressure during this step
The entire procedure takes approximately 15–20 minutes from start to finish.
Expected Outcomes
- Immediate effect: The local anaesthetic component provides rapid relief from arm pain shortly after the injection, with an effect lasting several hours. This immediate response also helps confirm that the targeted nerve level is the true source of the patient's symptoms.
- Sustained effect: The corticosteroid begins reducing nerve root inflammation progressively, reaching its full anti-inflammatory effect within 1–2 weeks.
- Duration: Patients who respond well typically experience meaningful reduction in radicular arm pain lasting 3–6 months or longer, depending on the severity of the underlying nerve compression and the individual patient's response.
Post-Procedure Care
Day of procedure:
- Rest for the remainder of the day; avoid strenuous physical activity
- Do not drive on the day of the procedure — mild dizziness is possible following the injection; arrange for a companion or use public transport
- The following day: Most patients can return to their normal daily activities.
- Injection site: Mild soreness or aching at the injection site is normal and expected. This typically resolves on its own within 1–2 days and should not be confused with a return of the original neck or arm pain.
Long-Term Prevention of Cervical Radicular Pain
- Appropriate equipment — choose a chair that supports the natural lumbar and cervical curve, and a pillow that maintains the neck's natural alignment during sleep; good ergonomic support reduces cumulative mechanical stress on the cervical discs and nerve roots.
- Exercise and stretching — regularly stretch the neck and shoulder muscles to maintain flexibility and reduce tension; strengthen the deep cervical stabiliser muscles and upper back to provide better mechanical support for the cervical spine; a physiotherapist can guide you on an appropriate exercise programme.
