Leg pain that originates in the back is one of the most disruptive pain patterns a person can experience. It changes how you sit, sleep, drive, and — for many patients in Northern Kentucky — how you work. Understanding what is causing the leg pain is the essential first step toward treating it effectively.
Dr. Erik Simms evaluates leg pain and sciatica at Triple Crown Chiropractic in Walton and Covington. The causes vary — herniated disc, piriformis compression, bone spurs, stenosis — but the evaluation process is the same: identify which structure is irritating the nerve, determine the severity, and build a conservative care plan that addresses the source.
Key Takeaways
- Leg pain originating from the spine is usually caused by a nerve root being compressed or irritated — most commonly by a herniated disc, bone spur, or tight piriformis muscle.
- True sciatica follows the path of the sciatic nerve from the low back through the buttock and down the back of the leg.
- Not all leg pain is sciatica — SI joint dysfunction, hip problems, and vascular causes can create similar symptoms.
- Progressive weakness, saddle numbness, or loss of bladder or bowel control are emergencies requiring immediate medical care.
- Triple Crown Chiropractic reports a 90% success rate treating sciatica with conservative care.
What is sciatica?
Sciatica describes symptoms — not a specific diagnosis. When someone says they have sciatica, they typically mean pain, numbness, tingling, or weakness that follows the sciatic nerve path from the low back through the buttock and down the back of the thigh, sometimes into the calf or foot.
The sciatic nerve is the largest nerve in the body. It exits the lumbar spine through roots at L4, L5, and S1, passes through the pelvis, and travels down the back of each leg. Compression or irritation of these nerve roots creates the characteristic radiating symptom pattern.
Most common causes of leg pain and sciatica
- Herniated lumbar disc — disc material pressing against a nerve root at L4, L5, or S1
- Lumbar bone spurs — arthritic changes that narrow the foramen through which the nerve exits
- Lumbar spinal stenosis — narrowing of the spinal canal that compresses multiple nerve roots
- Piriformis syndrome — the piriformis muscle in the buttock irritating the sciatic nerve as it passes beneath it
- Sacroiliac joint dysfunction — SI joint irritation that refers pain into the buttock and mimics sciatica
- Spondylolisthesis — vertebral slippage that compresses a nerve root
- Facet joint irritation — inflamed facet joints referring pain into the buttock or upper thigh
Leg Pain, Numbness, or Tingling?
Dr. Simms can evaluate whether sciatica, a herniated disc, or another cause is behind your symptoms — and build a conservative plan to address it.
Herniated disc — the most common cause
A lumbar disc herniation occurs when the inner material of a disc pushes through the outer wall and presses on an adjacent nerve root. The result is often intense, sharp, electric, or burning pain that radiates down the specific nerve path being compressed.
Warehouse workers, drivers, and manual laborers throughout Boone County who have experienced acute disc injuries from lifting often describe sciatica that began with a specific incident. But disc herniations can also build gradually from cumulative compression without a single memorable event.
Piriformis syndrome — the frequently missed cause
The piriformis is a small muscle deep in the buttock. In many people, the sciatic nerve passes directly beneath it — and in some individuals, directly through it. When the piriformis is tight, overworked, or in spasm, it can compress the sciatic nerve and create symptoms nearly identical to disc-related sciatica.
Piriformis syndrome is frequently missed because it does not show on MRI as a disc problem. If sciatica-like symptoms are not responding to lumbar-focused care, piriformis involvement is often the explanation.
How Dr. Simms evaluates leg pain and sciatica
- Detailed symptom history — onset, location, what worsens and improves it
- Neurological testing — reflexes, muscle strength, sensation along specific nerve distributions
- Orthopedic tests — straight leg raise, SLUMP test, piriformis provocation
- Movement pattern analysis — which positions and activities change symptoms
- Imaging review when available; referral for MRI when neurological findings suggest significant nerve compromise
What chiropractic care does for sciatica and leg pain
- Lumbar adjustments or mobilization to reduce joint restriction and mechanical nerve compression.
- Piriformis and hip soft tissue therapy to reduce extra-spinal nerve irritation.
- Disc care positioning and decompression protocols that reduce intradiscal pressure.
- Therapeutic exercise to stabilize the lumbar spine and support nerve recovery.
- Activity modification to reduce aggravating positions during healing.
“Sciatica is a symptom, not a diagnosis. Finding the actual cause is what makes the difference in how well and how quickly someone recovers.”

Frequently Asked Questions
What is the most common cause of sciatica?
A lumbar disc herniation at L4-L5 or L5-S1 is the most common cause of sciatica. The herniated disc material presses against a nerve root, creating pain, numbness, or tingling that radiates down the back of the leg. Piriformis syndrome, bone spurs, and spinal stenosis are also frequent causes.
How do I know if my leg pain is sciatica?
Sciatica typically causes pain, numbness, or tingling that starts in the low back or buttock and travels down the back of one leg, often into the calf or foot. It usually affects one leg at a time and can worsen with sitting, bending forward, or sneezing. A chiropractic exam can confirm whether sciatica is the cause.
Can a chiropractor help with sciatica?
Yes. Chiropractic care can help many cases of sciatica by reducing mechanical compression on the sciatic nerve through lumbar adjustments, disc care protocols, piriformis soft tissue therapy, and stabilization exercises. Triple Crown Chiropractic reports a 90% success rate treating sciatica.
How long does sciatica take to heal with chiropractic care?
Many patients notice meaningful improvement within the first 2–4 weeks of consistent chiropractic care. Full resolution depends on the cause — disc herniations may take 6–12 weeks, while piriformis-related sciatica often responds faster. Chronic sciatica takes longer.
Is there a difference between sciatica and lower back pain?
Yes. Lower back pain stays local to the lumbar region. Sciatica radiates into the buttock, thigh, calf, or foot following the nerve path. The two can occur together, and treatment for each can differ significantly. A proper evaluation is needed to distinguish them.
