Sciatica: Causes, Symptoms, and Treatment

Author: Marcus Drivas

What is Sciatica?

Sciatica is a common condition that causes pain, tingling, or numbness that radiates from the lower back down through the buttocks and into one or both legs. It occurs when the sciatic nerve, the longest nerve in the body, becomes irritated or compressed. The pain can range from mild discomfort to severe, debilitating pain that affects daily activities.

At Gladesville Healthcare, our experienced chiropractors and physiotherapists provide effective, evidence-based treatments to help relieve sciatica pain and prevent it from recurring.

What Causes Sciatica?

Sciatica is often caused by compression or irritation of the sciatic nerve, which can result from:

Herniated or bulging discs – A slipped disc in the lower spine can press on the sciatic nerve, causing pain.
Spinal stenosis – Narrowing of the spinal canal can put pressure on the nerve roots.
Piriformis syndrome – A tight or inflamed piriformis muscle in the buttock can compress the sciatic nerve.
Spondylolisthesis – A condition where one vertebra slips over another, potentially irritating the nerve.
Muscle tightness and poor posture – Prolonged sitting, improper lifting techniques, and muscular imbalances can contribute to nerve compression.

Common Symptoms of Sciatica

Sharp, shooting pain in the lower back, buttock, and down the leg.
Burning or tingling sensations along the path of the sciatic nerve.
Numbness or weakness in the leg or foot.
Pain that worsens with prolonged sitting, standing, or movement.

How Can GHC Help with Sciatica?

At Gladesville Healthcare, our chiropractors, physiotherapists, and podiatrists offer a comprehensive approach to sciatica treatment, focusing on long-term relief and prevention.

1. Thorough Assessment & Diagnosis

Our team will conduct a detailed physical examination to determine the root cause of your sciatica. If necessary, we may recommend further imaging, such as X-rays or MRIs, to assess spinal health.

2. Chiropractic & Physiotherapy Treatment

Our skilled practitioners use a combination of gentle spinal adjustments, joint mobilisation, and soft tissue therapy to relieve nerve pressure and restore movement.

3. Radial Shockwave Therapy

For chronic cases, Radial Shockwave Therapy can stimulate blood flow, break down scar tissue, and promote faster healing in affected areas.

4. Dry Needling & Soft Tissue Release

Tight muscles, especially in the lower back and glutes, can worsen sciatica pain. Our dry needling and soft tissue therapy techniques help release muscle tension and reduce nerve compression.

5. Targeted Strengthening & Stretching Exercises

We prescribe individualised rehab exercises to improve core strength, correct muscle imbalances, and reduce the likelihood of sciatic nerve compression in the future.

6. Postural & Ergonomic Advice

Sitting for long periods can aggravate sciatica. We offer expert ergonomic advice to improve posture at work, at home, and while exercising.
