Calming nerve inflammation
Corticosteroid medication bathes the irritated nerve roots in the epidural space, reducing the swelling that drives radiating pain.

Epidural Injections
Injections into the epidural space around the spinal nerves, used within interventional pain management.
What it is
Anti-inflammatory treatment at the nerve
An epidural steroid injection places corticosteroid medication into the fatty sleeve surrounding the spinal nerves. By calming inflammation at its source, it relieves the radiating pain of irritated roots — most successfully for disc herniation and stenosis. It manages pain; it does not cure the underlying wear.
Best for radicular pain
Most effective where a herniated disc or stenosis inflames specific roots — leg-dominant or arm-dominant pain rather than pure backache.
A window for rehab
Reduced nerve pain lets physiotherapy and normal movement resume — which is where lasting benefit is built.
Surgery-sparing option
Many inflamed nerves settle with targeted anti-inflammatory treatment, avoiding or deferring an operation.
What to expect
A brief, precise appointment
The procedure itself is short and performed with you awake, so you can report what you feel throughout.
01
Three routes, one space
Interlaminar, transforaminal or caudal paths reach the same epidural space; the approach is chosen by level and target, always under imaging guidance.
02
Medication effect
Anaesthetic gives immediate feedback; the steroid component builds over the days that follow. A brief flare first is common.
03
Aftercare
Rest briefly, arrange a driver, and report fever, worsening pain, new weakness or bladder changes promptly.
Common questions
Things patients ask us
How long does the relief last?
It varies — from weeks to many months, and occasionally longer. Relief that enables rehab counts as success even when it is temporary.
How many injections will I need?
As few as achieve the goal. Steroid exposure is deliberately limited, so your surgeon spaces treatments and stops when they no longer add benefit.
What are the risks?
Brief soreness, flushing and blood-sugar rises are commonest. Headache from dural puncture, infection, bleeding and nerve injury are uncommon; blood thinners, diabetes and allergies are reviewed beforehand.
Will I still need surgery?
Not necessarily. Nerves that settle with injections often stay settled — and if they do not, the response pattern sharpens any surgical plan.
