Signs Your Sciatica Is Caused by a Disc Injury
Sciatica is one of the most common reasons people seek chiropractic care. While many people use the term "sciatica" to describe any pain that travels down the leg, sciatica is actually a symptom—not a diagnosis. The underlying cause matters because the most effective treatment depends on what's irritating the sciatic nerve.
One of the most common causes of sciatica is a herniated or bulging spinal disc. At Tenckhoff Chiropractic in Brea, we specialize in diagnosing and treating disc injuries using Cox® Technic Flexion Distraction and spinal decompression to help patients find lasting relief without surgery whenever possible.
What Is Sciatica?
The sciatic nerve is the largest nerve in the body. It begins in the lower back and travels through the buttocks and down each leg. When the nerve becomes compressed or irritated, it can cause symptoms including:
Pain that radiates from the low back into the buttock and leg
Burning or electric shock-like sensations
Tingling or numbness
Muscle weakness
Pain that worsens with sitting
Many conditions can irritate the sciatic nerve, but disc injuries are among the most common.
6 Signs Your Sciatica May Be Caused by a Disc Injury
1. Your Pain Started After Lifting, Twisting, or Bending
Disc injuries often occur after:
Lifting something heavy
Twisting while carrying weight
Repeated bending
A car accident
Sports injuries
Sometimes patients don't notice severe pain immediately. Instead, the disc becomes injured, and symptoms worsen over several days as inflammation develops.
2. Sitting Makes Your Pain Worse
One of the hallmark signs of a disc injury is pain that increases while sitting.
Sitting places significantly more pressure on the spinal discs than standing or walking. Many patients notice:
Pain while driving
Difficulty sitting through work meetings
Relief when standing up or walking around
If your sciatica is much worse after prolonged sitting, a disc problem is more likely.
3. You Have Numbness or Tingling
A bulging or herniated disc doesn't just cause pain—it can interfere with normal nerve function.
Symptoms may include:
Pins and needles
Numbness in the foot
Tingling in the toes
Areas of decreased sensation
These symptoms suggest the nerve is being compressed rather than simply inflamed.
4. Coughing or Sneezing Makes It Worse
Many patients are surprised that coughing, sneezing, or straining can increase leg pain.
These activities temporarily increase pressure inside the spinal canal. If a disc is already pressing on a nerve root, that increased pressure can reproduce or intensify symptoms.
This is a classic sign that your sciatica may be disc-related.
5. You Notice Leg Weakness
If you find yourself:
Tripping more often
Having difficulty lifting your foot
Feeling like your leg "gives out"
Struggling to stand on your toes or heels
the affected nerve may not be sending normal signals to your muscles.
Weakness should always be evaluated promptly because prolonged nerve compression can lead to lasting deficits if left untreated.
6. Your Back Pain Improved—but Your Leg Pain Didn't
Many people assume that if their back pain improves, the injury is healing.
Ironically, with disc injuries, worsening leg pain alongside decreasing back pain can actually indicate that the disc is irritating the nerve more directly.
This phenomenon is one reason proper examination is so important.
How We Determine If a Disc Is the Cause
At Tenckhoff Chiropractic, we perform a thorough examination that may include:
Orthopedic testing
Neurological evaluation
Reflex testing
Muscle strength testing
Sensory examination
Movement assessment
If necessary, we may recommend advanced imaging such as an MRI to evaluate the health of your spinal discs.
The goal is not simply to diagnose "sciatica," but to identify why you're experiencing it.
Can Disc-Related Sciatica Heal Without Surgery?
In many cases, yes.
Most disc injuries improve with conservative treatment. Research has shown that many herniated discs gradually shrink over time as the body naturally reabsorbs disc material.
Treatment often focuses on:
Reducing pressure on the affected nerve
Improving spinal movement
Decreasing inflammation
Restoring normal function
Early treatment may also help prevent symptoms from becoming chronic.
Why We Use Cox® Technic Flexion Distraction
Not all chiropractic techniques are appropriate for disc injuries.
At Tenckhoff Chiropractic, we are certified in Cox® Technic Flexion Distraction, a gentle, research-supported treatment specifically designed for spinal disc conditions.
Unlike traditional twisting or high-force adjustments, Cox® Technic uses a specialized treatment table to gently decompress the affected spinal segment. This approach aims to:
Reduce pressure on irritated nerves
Improve spinal mobility
Lower pressure inside the injured disc
Help patients move with less pain

When Should You Seek Care?
You should schedule an evaluation if your sciatica:
Lasts more than a few days
Is becoming more severe
Travels below the knee
Includes numbness or tingling
Makes sitting difficult
Interferes with work or daily activities
Seek emergency medical care immediately if you experience loss of bowel or bladder control, numbness in the groin area (saddle anesthesia), or rapidly worsening leg weakness, as these symptoms may indicate a medical emergency.
