Types Of Injections For Back Pain

Last updated on January 29, 2025

Back pain is a common health issue in Australia, affecting people of all ages and activity levels. Whether caused by injuries, chronic conditions, or poor posture, back pain can significantly impact daily life.

There are non-surgical options that may assist with managing this pain effectively, including various types of injections for back pain. These injections are designed to target pain and inflammation directly and may offer relief and improve quality of life.

In this guide, we’ll explore the most common types of spinal injections, their uses, benefits, and risks, along with answers to frequently asked questions.

Types of Injections for Back Pain

1. Epidural Steroid Injections

Epidural steroid injections are among the most common treatments for back pain caused by nerve irritation or inflammation, such as sciatica, herniated discs, or spinal stenosis.

  • How They Work: The injection is administered into the epidural space surrounding the spinal cord, delivering corticosteroids to reduce inflammation and pain.
  • What to Expect: Pain relief may occur within a few days and can last from weeks to months, depending on the condition.

Ideal For:

  • Sciatica and other nerve-related back pain.
  • Pain caused by inflammation of the spinal nerves.

Advantages:

  • Minimally invasive and non-surgical.
  • Can provide significant pain relief, improving mobility.

Disadvantages:

  • Relief is often temporary, requiring follow-up treatments.
  • May not be suitable for all patients, such as those with infections or bleeding disorders.

2. Facet Joint Injections

Facet joints are small joints in the spine that provide stability and enable movement. When these joints become inflamed or damaged, they can cause chronic back pain.

  • Purpose: A facet joint injection is both diagnostic and therapeutic, helping identify the source of pain while also delivering relief.
  • Procedure: A mixture of corticosteroids and local anaesthetics is injected into the facet joints.

Ideal For:

  • Arthritis-related back pain.
  • Pain localised to the spine due to facet joint issues.

Advantages:

  • Immediate feedback on whether the facet joints are causing the pain.
  • Can improve mobility and reduce inflammation.

Disadvantages:

  • Pain relief may be short-lived, requiring repeat injections.
  • Effectiveness depends on accurate diagnosis.

Trigger point injections may assist with muscle pain and tension.

3. Trigger Point Injections for Back Pain

Trigger points are tight knots of muscle that can cause localised or referred pain. These injections are used to alleviate myofascial pain caused by these knots.

  • Components: Injections may contain saline, anaesthetic, or corticosteroids to relax the muscle and reduce pain.
  • Procedure: Administered directly into the painful muscle areas.

Ideal For:

  • Muscle pain and tension.
  • Chronic conditions like myofascial pain syndrome.

Advantages:

  • Immediate relief from localised pain.
  • Can improve range of motion and decrease muscle stiffness.

Disadvantages:

  • The relief from trigger point injections may be short-lived, especially if the underlying cause of the muscle tension is not addressed.
  • Trigger point injections treat the symptoms (pain and muscle knots) rather than the root cause of the issue

4. Nerve Block Injections

Nerve block injections are designed to interrupt pain signals from specific nerves. These injections are both diagnostic and therapeutic.

  • How They Work: A local anaesthetic is injected near the targeted nerve to block pain signals.
  • Applications: Often used in preparation for radiofrequency ablation procedures or to diagnose the source of nerve pain.

Ideal For:

  • Chronic nerve-related back pain.
  • Conditions like spinal stenosis or radiculopathy.

Advantages:

  • May be effective at providing temporary relief and pinpointing pain sources.
  • Minimally invasive with minimal recovery time.

Disadvantages:

  • Temporary relief; additional treatments are often needed.

5. Sacroiliac Joint Injections

The sacroiliac (SI) joints, located where the spine meets the pelvis, can become inflamed or arthritic, causing significant lower back pain.

  • How They Help: SI joint injections reduce inflammation and relieve pain by delivering corticosteroids and anaesthetics.

Ideal For:

  • Pain originating from the lower back and pelvis.
  • Conditions like sacroiliitis or SI joint dysfunction.

Advantages:

  • Targeted pain relief for SI joint issues.
  • Helps improve mobility and reduce inflammation.

Disadvantages:

  • Pain relief from sacroiliac (SI) joint injections is often temporary, lasting weeks to a few months.
  • While SI joint injections can confirm that the SI joint is the source of pain, they do not identify the underlying cause of the inflammation or dysfunction.

There are a few potential benefits of spinal injections for back pain.

Benefits of Spinal Injections for Back Pain

  • Targeted Relief: Injections are directed precisely at the source of pain, making them potentially highly effective for specific conditions.
  • Minimally Invasive: Avoid the risks and recovery time associated with surgery.
  • Versatility: Suitable for various back pain causes, from muscle tension to nerve compression.
  • Improved Mobility: Pain relief may help patients return to normal activities.
  • Complementary Treatment: Often used alongside physical therapy and other treatments for comprehensive pain management.

Risks and Considerations

Although spinal injections are generally safe, it’s essential to be aware of potential risks:

  • Mild side effects like soreness, swelling, or temporary pain flare-ups.
  • Rare complications such as infection, bleeding, or nerve damage.
  • Effectiveness may vary based on the individual and underlying condition.

Always discuss your medical history and treatment goals with your healthcare provider to determine the best option.

The best injection for pain relief depends on the specific cause and type of back pain. For nerve-related pain, an epidural steroid injection or selective nerve root block is often recommended to reduce inflammation around the spinal cord or nerve roots. For muscle-related pain, trigger point injections may be more suitable. At Vein Doctors Sydney, we will assess your condition and recommend the most appropriate type of spinal injection to effectively treat pain.

Yes, spinal injections may be effective for managing chronic pain. Procedures such as epidural steroid injections and facet joint injections target inflammation and pain at its source, providing temporary but significant relief. For some individuals with long-term conditions like arthritis or nerve compression, these treatments may greatly improve quality of life. However, injections are often part of a broader pain management plan, including physical therapy and lifestyle adjustments.

A selective nerve root block involves injecting a combination of anaesthetic and corticosteroid near the specific nerve root causing pain. This procedure temporarily blocks pain signals to the brain while reducing inflammation in the affected area. It is particularly effective for conditions like leg pain associated with sciatica or herniated discs. By identifying the exact source of pain, a nerve root block may also help guide further treatment plans.

Relief from an epidural steroid injection varies depending on the individual and the underlying condition. Many patients experience significant pain relief for several weeks to months, particularly if the pain originates from inflammation around the spinal cord or nerve roots. While this treatment is not a permanent cure, it may help manage symptoms and improve daily functioning, especially in cases of sciatica or spinal stenosis.
