Disc Pain & Sciatica: Understanding the Cause and Getting Back to Living

If you've ever experienced pain shooting down your leg, numbness in your foot, or struggled to stand up after sitting, there's a good chance you've heard the term sciatica. While sciatica itself isn't a diagnosis, it's often a sign that a spinal disc or another spinal structure is irritating the sciatic nerve.

The good news? Many people can improve with the right diagnosis, movement, and care plan.

What Causes Disc Pain & Sciatica?

Between each bone in your spine sits a spinal disc. Think of these discs as shock absorbers that allow your spine to move while protecting it from everyday forces.

Over time, or after an injury such as lifting incorrectly, repetitive bending, prolonged sitting, or even a sudden twist, a disc can become irritated or injured. Sometimes the disc bulges or herniates, placing pressure on nearby nerves, including the sciatic nerve.

Common causes include:

• Prolonged sitting or poor posture

• Repetitive lifting or twisting

• Heavy manual work

• Sporting injuries

• Age-related disc degeneration

• Weak core and glute muscles

• Reduced spinal mobility

What Does It Feel Like?

Everyone experiences disc pain differently, but common symptoms include:

• Low back pain

• Pain travelling into the buttock, thigh, calf or foot

• Sharp, burning or electric-like pain

• Pins and needles or numbness

• Muscle weakness in the leg

• Pain that worsens when sitting, coughing or sneezing

• Difficulty standing up straight after sitting

Some people feel only back pain, while others experience very little back pain but significant leg pain.

What do I do?

At Back for the Future Chiropractic, our first goal is to determine whether your symptoms are coming from a disc, a joint, muscles, or another condition.

Your chiropractor will complete a thorough assessment, which may include:

• Orthopaedic and neurological testing

• Movement assessment

• Postural evaluation

• X-rays or a referral for MRI when clinically appropriate

Once we understand what's causing your symptoms, we'll develop an individualised care plan.

Depending on your condition, chiropractic care may help by:

• Improving spinal mobility

• Reducing stress on irritated joints and surrounding tissues

• Encouraging better movement patterns

• Helping decrease muscle tension and protective spasms

• Supporting your body's natural recovery process

• Improving function so everyday activities become easier

Treatment may include gentle chiropractic adjustments, soft tissue therapy, mobility exercises, posture advice, and rehabilitation exercises.

Exercises That May Help

Movement is often one of the best medicines for many people with disc-related pain, although the right exercise depends on the individual. Always stop if an exercise significantly increases your leg pain.

Walking

A gentle daily walk encourages blood flow, reduces stiffness, and keeps the spine moving without excessive loading.

Prone Press-Ups (Extension Exercise)

Lie on your stomach and gently press your upper body up using your arms while keeping your hips on the floor. This movement may help some people whose symptoms improve with extension.

Perform 10 repetitions every few hours if comfortable.

Pelvic Tilts

Lie on your back with knees bent. Gently flatten your lower back into the floor before relaxing.

Repeat 10-15 times.

Bird Dog

Begin on your hands and knees. Slowly extend one arm and the opposite leg while keeping your spine stable.

Hold for 5-10 seconds and repeat 8-10 times each side.

Gentle Hamstring Stretch

Tight hamstrings can increase tension through the lower back. Stretch gently without forcing the movement or reproducing sharp leg pain.

Glute Bridges

Strengthening the glutes helps reduce strain on the lower back and improves spinal support.

Complete 2-3 sets of 10 repetitions.

When Should You Seek Help?

Many people wait until their pain becomes severe before seeking help. Unfortunately, by that stage the problem has often been present for much longer, making recovery more difficult and, in many cases, taking longer than if it had been addressed early.

If you're noticing persistent pain, numbness, tingling, weakness, or symptoms that keep coming back, it's worth getting checked sooner rather than later. Early assessment and appropriate care can help prevent small problems from becoming bigger ones and get you back to doing the things you love sooner.

While most cases improve with conservative management, you should seek urgent medical attention if you experience:

• Loss of bladder or bowel control

• Numbness around the groin or saddle region

• Rapidly worsening leg weakness

• Severe pain following major trauma

These symptoms require immediate medical assessment.

The Bottom Line

Disc pain and sciatica can be frustrating, but they don't have to control your life. Early assessment, staying active where appropriate, and following an evidence-informed treatment plan can help many people reduce pain, restore movement, and return to the activities they enjoy.
