Sciatica

INJECTION FOR SCIATICA

Understanding Sciatica

Sciatica refers to pain that follows the path of the sciatic nerve, the largest nerve in the human body. It typically affects one side of the body, causing pain that begins in the lower back and radiates down the buttock, thigh, and leg, often extending to the foot.

At Alton Pain Clinic, our clinicians specialise in image-guided pain management and offer ultrasound-guided injections for sciatica, including Caudal epidural injections and Nerve Block Injection. These targeted treatments aim to relieve pain and inflammation caused by irritation or compression of the sciatic nerve.

Symptoms

Sciatica is characterised by more than just back pain. Its hallmark is radiating nerve pain that follows the sciatic nerve’s trajectory. Typical symptoms include:

  • Shooting pain down one leg
  • Numbness or tingling in the foot or toes
  • Burning or electric-like pain
  • Weakness in the affected leg
  • Pain that worsens with sitting, coughing, or bending forward
  • Difficulty walking or standing due to discomfort

The intensity can range from mild to severe and may be constant or intermittent.

Injection for Sciatica

Injections for Sciatica at Alton Pain Clinic

Our clinic offers ultrasound-guided injections for sciatica, which allow our clinicians to deliver anti-inflammatory medication directly to the source of nerve irritation.

We specialise in two main types of injection for sciatica pain:

A caudal epidural injection is a commonly used treatment for lower back and leg pain caused by sciatic nerve inflammation.

What It Involves

  • The injection is delivered through the sacral hiatus at the base of the spine into the epidural space.
  • A mixture of local anaesthetic and corticosteroid is administered to reduce inflammation and relieve nerve compression.

Benefits

  • Reduces inflammation and nerve root swelling
  • Alleviates radiating leg pain
  • Improves mobility and function
  • Non-surgical and minimally invasive
  • Can reduce reliance on oral medication

Mechanism of Action

The steroid works to suppress inflammation, thereby relieving pressure on the sciatic nerve. The local anaesthetic provides rapid pain relief by temporarily blocking pain signal transmission. The combination promotes healing while allowing patients to resume activity more comfortably.

A nerve block injection is another targeted treatment we offer, aimed at interrupting pain signals transmitted from specific spinal nerve roots.

What It Involves

  • The injection is delivered near the exiting nerve root, typically at L4, L5, or S1.
  • A blend of steroid and anaesthetic is administered to provide both immediate and longer-term relief.
  • Ultrasound guidance enhances precision and safety.

Benefits

  • Reduces nerve-related leg pain
  • Helps confirm the exact source of sciatica
  • May delay or avoid the need for surgery

Mechanism of Action

The nerve block dampens abnormal nerve activity by delivering anaesthetic to the irritated nerve root, reducing pain signal transmission. The steroid further helps calm inflammation, prolonging the therapeutic effect.

Patient Reviews

Anatomy of the Sciatic Nerve

The sciatic nerve arises from the lumbosacral spine, specifically the nerve roots of L4 to S3, which combine to form a single, thick nerve. It exits the pelvis through the greater sciatic foramen, passing underneath the piriformis muscle, and continues along the back of the thigh, branching into smaller nerves at the knee that extend down to the feet.

Its primary function is to supply motor and sensory innervation to the lower limb. Given its extensive course, it is susceptible to compression or irritation at multiple anatomical points, particularly in the lower back or pelvis.

Causes of Sciatica

1. Herniated or Bulging Disc: A disc in the lumbar spine may protrude and press on the nerve root, causing inflammation and pain.

2. Lumbar Spinal Stenosis: Narrowing of the spinal canal compresses the sciatic nerve roots.

3. Degenerative Disc Disease: Wear and tear of the spinal discs can irritate nearby nerves.

4. Spondylolisthesis: A vertebra slipping over another can compress sciatic nerve roots.

5. Piriformis Syndrome: The sciatic nerve passes underneath or through the piriformis muscle in the buttocks. Tightness or spasm of this muscle may entrap the nerve.

6. Trauma or Postural Issues: Injury, falls, or prolonged poor posture can trigger or worsen sciatic symptoms.

Risk Factors

Several risk factors make individuals more likely to develop sciatica:

  • Age – Disc degeneration is common with ageing
  • Occupation – Jobs requiring heavy lifting or prolonged sitting
  • Sedentary lifestyle – Lack of movement can increase spinal stiffness
  • Obesity – Excess weight places pressure on the spine
  • Diabetes – May lead to peripheral nerve damage
  • Pregnancy – The growing uterus may compress the sciatic nerve

Diagnosis and Clinical Assessment

At Alton Pain Clinic, our clinicians perform a thorough assessment that includes:

  • Medical history and symptom discussion
  • Physical examination, including straight leg raise and neurological tests
  • Diagnostic ultrasound, where appropriate, to guide treatment

Understanding the exact cause of sciatic pain is key to tailoring the most appropriate and effective treatment plan.
