Epidural Steroid Injection

An anti-inflammatory placed directly next to the irritated nerve root, under live X-ray guidance.

What it is

The epidural space surrounds the spinal nerves. When a disc herniation inflames a nerve root, much of the pain is chemical rather than purely mechanical — the inflammatory soup around the nerve is doing a great deal of the work. Placing corticosteroid there addresses that directly, at a dose far smaller than tablets would require for the same local effect.

What we use it for

• Sciatica from a lumbar disc herniation
• Cervical radiculopathy with arm pain
• Spinal stenosis with walking limitation
• Persistent radiating pain after an accident

What to expect

• You lie face down. The skin is numbed.
• Live fluoroscopy is used to place the needle — contrast confirms position before any medication is given.
• The injection takes a few minutes. Most people describe pressure rather than pain.
• You rest briefly and go home. You will need someone to drive you.
• Relief may be immediate from the local anaesthetic, fade after a few hours, then build again over three to seven days as the steroid works.

Risks

Every injection carries a small risk of bleeding, infection, an allergic reaction, or a temporary increase in pain. Steroid can raise blood sugar for several days, which matters if you are diabetic. Serious complications are rare, and we will go through the specific risks for your procedure and your health before you consent to anything.
