CAUDAL EPIDURAL INJECTION
A caudal epidural injection is a minimally invasive treatment that may help reduce lower back and leg pain caused by irritation or inflammation around the nerves in the lower spine. At Alton Pain Clinic, caudal epidural injections are performed using ultrasound guidance to help accurately identify the treatment area and guide the injection.
A caudal epidural injection may be considered for conditions such as sciatica, nerve root irritation, spinal stenosis and certain disc-related conditions. Your clinician will assess your symptoms and medical history to determine whether this treatment is appropriate for you.
What Is a Caudal Epidural Injection?
A caudal injection is an injection delivered into the epidural space at the lower end of the spine through an opening in the sacrum called the sacral hiatus. The epidural space surrounds the spinal nerves, and medication can be delivered into this area to help reduce inflammation and pain.
A caudal epidural injection commonly contains a corticosteroid, which has an anti-inflammatory effect. A local anaesthetic may also be used as part of the injection, depending on the treatment plan.
The term caudal ESI injection is another way of describing a caudal epidural steroid injection. You may also see the treatment referred to simply as a caudal injection or, informally, a “caudal inj”.
What Conditions Can a Caudal Epidural Injection Treat?
- Sciatica causing pain that travels from the lower back into the buttock or leg
- Herniated or bulging disc that irritate nearby spinal nerves
- Spinal stenosis, where narrowing around the spinal nerves may contribute to pain
- Nerve root irritation or inflammation
- Degenerative disc disease associated with lower back pain
- Certain cases of persistent lower back and radiating leg pain
Not everyone with these conditions will benefit from an epidural injection. Your clinician will assess your symptoms and discuss whether a caudal approach is appropriate for you.
How Does a Caudal Epidural Injection Work?
The aim of a caudal epidural injection is to deliver anti-inflammatory medication close to the affected nerves in the lower spine.
When spinal nerves become irritated or inflamed, they can cause pain that travels from the lower back into the buttocks or legs. Corticosteroid medication may help reduce inflammation around these nerves, which can provide temporary pain relief for some patients.
The response to treatment varies between individuals. Some people experience improvement relatively quickly, while others may take several days to notice the effect.
The purpose of the injection is generally to help manage pain and improve function. It is not intended to repair structural changes such as a disc herniation or spinal narrowing.
What Happens During a Caudal Epidural Injection?
If a caudal epidural injection is considered appropriate, the procedure will be explained to you before treatment.
During the procedure:
- You will be positioned comfortably, usually lying face down.
- The skin around the lower spine and sacral area will be cleaned carefully.
- Local anaesthetic may be used to numb the skin and reduce discomfort.
- Ultrasound guidance is used to help identify the relevant anatomy and guide the procedure.
- The needle is introduced through the sacral hiatus towards the epidural space.
- The prescribed medication is administered.
- The needle is removed and the injection site is checked.
The procedure itself is usually relatively quick, although your overall appointment will take longer because of preparation and assessment.

Why Is Ultrasound Guidance Used?
At Alton Pain Clinic, caudal epidural injections are performed using ultrasound guidance.
Ultrasound allows the clinician to visualise relevant anatomical structures in real time while performing the procedure. This helps guide the needle towards the intended area and avoids the use of ionising radiation.
Ultrasound guidance can form part of a careful, targeted approach to injection treatment, although no procedure is completely risk-free.
Benefits of a Caudal Epidural Injection
Depending on the underlying cause of your symptoms, potential benefits may include:
- Reduction in inflammation around irritated spinal nerves
- Temporary relief from lower back pain
- Reduction in radiating leg pain or sciatica symptoms
- Improved ability to move and carry out daily activities
- Potentially reduced reliance on pain medication for some patients
- A minimally invasive treatment option that can be considered before more invasive interventions
The degree and duration of pain relief vary from person to person. Your clinician will discuss the expected benefits based on your individual symptoms.
Is a Caudal Epidural Injection Painful?
You may feel some discomfort when the local anaesthetic and injection are administered. Local anaesthetic can be used to make the procedure more comfortable.
Some patients experience temporary soreness around the injection site afterwards. If you experience significant or persistent pain following the procedure, you should contact your clinician for advice.
How Long Does a Caudal Epidural Injection Take?
The injection procedure itself usually takes around 15–30 minutes, although the total appointment may be longer to allow time for assessment, preparation and post-procedure advice.
You will receive specific instructions from your clinician about what to expect after your injection and when you can return to your usual activities.
When Will a Caudal Epidural Injection Start Working?
The timing of pain relief varies between patients.
The local anaesthetic, if used, may provide relatively rapid but temporary relief. The corticosteroid component may take longer to have an anti-inflammatory effect, and some patients may notice improvement over the following days.
A caudal epidural injection does not guarantee immediate or complete pain relief, and the response depends on factors including the underlying condition and individual response to treatment.
Caudal Epidural Injection at Alton Pain Clinic
At Alton Pain Clinic, we provide ultrasound-guided caudal epidural injections as part of our advanced spinal pain management services.
Our approach begins with an assessment of your symptoms and medical history. Where appropriate, your clinician can discuss the available treatment options with you and explain the potential benefits and risks of a caudal epidural injection.
The aim is to provide a targeted treatment approach while ensuring that you understand what the procedure involves before deciding whether to proceed.
If you are experiencing persistent lower back or leg pain, contact Alton Pain Clinic to arrange an assessment.
Frequently Asked Questions
What is a caudal inj?
“Caudal inj” is a shortened term for a caudal injection or caudal epidural injection. It involves delivering medication into the epidural space through the sacral hiatus at the base of the spine.
Is a caudal injection the same as an epidural steroid injection?
A caudal injection can be a type of epidural steroid injection. The term describes the route used to access the epidural space, with the medication delivered through the sacral hiatus at the lower end of the spine.
What is a caudal ESI injection?
A caudal ESI injection means a caudal epidural steroid injection. It involves delivering corticosteroid medication into the epidural space through the sacral hiatus, with the aim of reducing inflammation around irritated spinal nerves.
What is the ESI injection cost at Alton Pain Clinic?
For a caudal epidural injection, the current listed price is £995. Other types of spinal injections may have different prices, so your clinician will advise which treatment is appropriate for your symptoms.
How quickly can I return to normal activities?
Your clinician will provide individual aftercare advice. The appropriate timeframe can depend on the procedure performed, your symptoms and how you respond to treatment.
Is a caudal epidural injection suitable for everyone with back pain?
No. Lower back pain has many possible causes, and an epidural injection is not appropriate for every type of back pain. An assessment is needed to determine whether a caudal epidural injection is suitable for your symptoms.
