No, a facet joint injection is not the same as an epidural injection. Although both are commonly used to treat spinal pain and may contain similar medications, they target different areas of the spine and are used for different conditions.
Understanding the difference between these two treatments can help patients make informed decisions about their care and understand why one may be recommended over the other.
What Is a Facet Joint Injection?
Facet joints are small joints located at the back of the spine that help provide stability and allow movement. Like other joints in the body, they can become inflamed, irritated, or affected by arthritis.
A facet joint injection involves injecting medication directly into or around the affected facet joint to reduce inflammation and relieve pain.
Facet joint injections are commonly used to treat:
- Facet joint syndrome
- Spinal osteoarthritis
- Chronic neck pain
- Chronic lower back pain
- Pain caused by degenerative changes in the spine
At Alton Pain Clinic, facet joint injections are performed under ultrasound guidance to improve accuracy and target the source of pain.
What Is an Epidural Injection?
An epidural injection is administered into the epidural space, which surrounds the spinal nerves.
Unlike facet joint injections, epidurals are primarily used when pain is caused by inflammation or irritation of spinal nerves.
Epidural injections are commonly recommended for:
- Sciatica
- Slipped (herniated) discs
- Spinal stenosis
- Nerve root irritation
- Leg pain caused by compressed nerves
The aim is to reduce inflammation around the affected nerve and improve symptoms such as radiating pain, numbness, or tingling.
What Is the Difference Between a Facet Joint Injection and an Epidural?
| Facet Joint Injection | Epidural Injection |
|---|---|
| Targets facet joints | Targets spinal nerves |
| Used for joint-related back or neck pain | Used for nerve-related pain |
| Commonly treats spinal arthritis | Commonly treats sciatica and nerve compression |
| Injected into or around a facet joint | Injected into the epidural space |
Although both treatments may contain corticosteroid medication, they are designed to address different causes of pain.
Which Injection Is Right for You?
The most appropriate treatment depends on the underlying cause of your symptoms.
A facet joint injection may be recommended if your pain is caused by:
- Facet joint inflammation
- Spinal arthritis
- Mechanical back pain
An epidural injection may be recommended if your symptoms are caused by:
- Sciatica
- Nerve compression
- A slipped disc
- Pain radiating into the legs
A clinical assessment and review of imaging studies can help determine which treatment is most suitable.
Are Facet Joint Injections and Epidurals Equally Effective?
Both treatments can be effective when used for the correct condition. However, neither treatment is suitable for every type of back pain.
The best results are usually achieved when the injection targets the specific source of pain, whether that is a facet joint or an irritated spinal nerve.
Key Takeaway
While facet joint injections and epidural injections are both used to manage spinal pain, they are not the same procedure. Facet joint injections target inflamed spinal joints, whereas epidural injections target irritated or compressed spinal nerves.
A thorough assessment can help identify the source of your pain and determine which treatment is most likely to provide relief.

Frequently Asked Questions
Is a facet joint injection the same as an epidural?
No. A facet joint injection targets the facet joints in the spine, while an epidural injection is delivered into the epidural space around the spinal nerves.
What is a facet joint injection used for?
Facet joint injections are used to treat back pain or neck pain caused by inflamed, arthritic, or irritated facet joints.
What is an epidural injection used for?
Epidural injections are commonly used to treat sciatica, slipped discs, spinal stenosis, and other conditions involving irritated spinal nerves.
Which is better: a facet joint injection or an epidural?
Neither is better for every condition. The most effective treatment depends on the source of your pain and the underlying spinal problem.
Does a facet joint injection contain a steroid?
Yes, facet joint injections often contain a corticosteroid and a local anaesthetic to help reduce inflammation and relieve pain.
