Epidural Steroid Injection

An epidural steroid injection delivers a corticosteroid into the epidural space around the spinal nerves. A local anaesthetic may be added to provide short-term numbing and help confirm the pain source. The injection is intended to calm inflammation around an irritated nerve; it does not remove a disc, widen a narrowed canal, or repair a structural problem.

An epidural steroid injection places anti-inflammatory medicine near irritated spinal nerves to reduce radiating pain for selected patients. The local anaesthetic can briefly numb pain soon after the procedure, while the corticosteroid may take additional time to settle inflammation. Benefit may be partial or temporary, and numbness or weakness from nerve compression can take longer to change.

Temporary soreness, pressure, flushing, headache, dizziness, or a short-lived increase in pain may occur. Steroid effects can include sleep or mood changes and a temporary rise in blood glucose. Uncommon but important problems include infection, bleeding, allergic reaction, nerve injury, or spinal-fluid headache. New weakness, fever, severe headache, or loss of bladder or bowel control needs urgent assessment.

This is a single injection rather than a daily treatment, although some people may discuss a later injection if symptoms return and the clinician considers it appropriate. The duration of relief varies. The injection should support a wider plan that may include movement, physiotherapy, activity changes, or treatment of the underlying cause.

Injections can be directed toward the neck, mid-back, or lower back depending on the nerve pattern. They are commonly considered for conditions such as Cervical Radiculopathy, Sciatica, Spinal Stenosis, or a Herniated Disc when symptoms match the examination and imaging. A C-Arm Fluoroscopy system may help guide placement.

A clinician may consider this injection when pain travels along a nerve pathway and inflammation is thought to contribute. Lower Back Pain or Radiating Leg Pain alone does not establish that an epidural injection is suitable. The decision includes the pain pattern, neurological examination, imaging, medicines, diabetes or bleeding risk, infection risk, and the goals of treatment.

You review medicines and health conditions, then lie in a position that exposes the target area. After cleaning and numbing the skin, the clinician advances a needle while using imaging guidance and may inject contrast to check the route. The corticosteroid, sometimes with local anaesthetic, is delivered near the intended nerve area before the needle is removed and the site covered.

You are observed briefly for changes in strength, sensation, blood pressure, or pain. Arrange transport if sedation is used, and follow instructions about driving and strenuous activity. Keep the injection site clean and record changes in pain, walking, sleep, or function. A flare can occur before improvement; contact the clinic if symptoms are severe, progressive, or accompanied by warning signs.

Risks include infection, bleeding, allergic reaction, temporary nerve irritation, spinal-fluid headache, and injury to nearby structures. Corticosteroid exposure can affect glucose, sleep, mood, or other medical conditions. Tell the clinician about blood thinners, diabetes, pregnancy possibility, allergies, fever, or a current infection before treatment.

Depending on the cause, options include physiotherapy, activity modification, oral medicines, other injections, or observation. If a disc fragment is creating persistent nerve compression, Microdiscectomy may be discussed. Progressive weakness, serious neurological findings, or an unsuitable injection target may require a surgical or urgent evaluation instead.

Choose a clinician experienced in image-guided spinal injections and ask which nerve or space will be targeted and why. Discuss expected goals, alternatives, medicine-related risks, aftercare, and the plan if pain returns. Bring your scan reports, medication list, allergy history, and a description of any numbness or weakness.
