Overview
When a spinal nerve becomes inflamed due to disc bulge spinal stenosis or degenerative changes pain may travel from the lower back into the buttock or leg. Epidural steroid injections deliver anti inflammatory medication directly into the epidural space surrounding the nerves.
This approach may provide short to medium term pain relief and can support physiotherapy by making movement more comfortable. In some cases it also helps confirm whether a specific nerve root is contributing to symptoms.
Who This Treatment Helps
• Sciatica or leg pain caused by nerve irritation
• Disc bulges or herniations
• Spinal stenosis
• Persistent low back pain with nerve related features
• Pain not improving with conservative treatment
• Difficulty engaging in rehabilitation due to pain
What Is an Epidural Steroid Injection
A fine needle is placed into the epidural space and a combination of steroid and local anaesthetic is delivered. Imaging guidance is used to ensure accurate placement. The procedure aims to reduce inflammation rather than correct structural spinal changes.
What to Expect During the Procedure
Consultant review and planning
Comfortable positioning
Local anaesthetic to numb the skin
Image guided needle placement
Medication delivery
Brief monitoring before discharge
After the Procedure
Temporary numbness or heaviness may occur
Mild soreness is common
Pain relief may develop gradually
Physiotherapy is often encouraged

When to Consider Other Options
Facet joint treatment nerve root blocks physiotherapy or other minimally invasive procedures may be discussed if symptoms persist.
