Sciatica

Sciatica refers to leg pain that originates in the lower back and radiates down the leg, often into the foot and toes. The sciatic nerve (about the diameter of your pinky finger) — the largest nerve in the body — which travels from the lower spine through the hips and down each leg. Rather than a single diagnosis, sciatica describes a pattern of symptoms resulting from underlying spinal or nerve dysfunction.

Many patients experience sciatic pain as sharp, shooting, or radiating discomfort extending from the lower back into the buttock, thigh, or even the foot. In some cases, symptoms include numbness, tingling, or muscle weakness. Because sciatic nerve irritation often originates in the lumbar spine, accurate evaluation is critical to determine the true source of compression or inflammation.

At Integrative Health and Rehabilitation, our Denver chiropractic clinic provides comprehensive, non-surgical treatment for sciatica. Our approach focuses on restoring spinal mobility, reducing disc and joint stress, calming nerve irritation, and improving muscular balance to support long-term recovery.

Common Causes of Sciatica

Sciatica symptoms typically develop when the sciatic nerve becomes irritated or compressed along its pathway.

Common underlying causes include:

• Lumbar disc bulging or herniation
• Degenerative disc disease
• Spinal joint dysfunction
• Facet inflammation
• Piriformis muscle irritation
• Lumbar spinal stenosis
• Traumatic injuries or auto accidents

Most patients with sciatica also have a history of lower back pain. There are several possible issues in the lower back that cause sciatica.

3 Most Common Causes of Sciatica

• Vertebral Subluxation
• Lumbar Disc Herniation
• Piriformis Syndrome

Treatment Options for Sciatica

Most cases of sciatica respond well to conservative, non-surgical care focused on relieving nerve pressure and restoring proper spinal mechanics.

Chiropractic Care

Targeted chiropractic adjustments improve lumbar joint motion, reducing stress on joints and spinal discs and relieving pressure on nerve roots.

Acupuncture

Acupuncture increases localized blood flow to injured tissues, bringing in nutrients and flushing toxins. It also reduces muscle spasms and provides competing, non-painful stimuli to interrupt pain signals from injured tissues.

Dry Needling

Dry needling is especially effective in addressing trigger points (bundles of muscle fibers that “stick together”), such as piriformis syndrome, which can contribute to sciatic nerve irritation.

Shockwave Therapy (ESWT)

Extracorporeal shockwave therapy may support tissue healing in chronic soft-tissue contributors to sciatic pain.

Low-Level Laser Therapy

Low-level laser therapy simulates photoreceptors in muscles, nerves, tendons, and ligaments to stimulate ATP production. ATP is crucial for optimal cellular function, including injury healing.

By combining therapies when appropriate, treatment can reduce nerve compression while improving flexibility and muscular support.

Symptoms Associated With Sciatica

Sciatica symptoms typically affect one side of the body and may include:

• Radiating pain from the lower back into the leg
• Burning or shooting discomfort
• Numbness or tingling in the leg or foot
• Muscle weakness
• Increased pain when sitting

In severe cases, symptoms may interfere with walking or standing for extended periods. Persistent neurological deficits should be evaluated promptly.

What Causes Sciatic Nerve Irritation?

The sciatic nerve originates from nerve roots in the lower lumbar spine. When discs bulge or herniate, they may press against nearby nerve roots. Similarly, joint inflammation or degenerative changes can narrow the spaces through which nerves exit the spine.

Initially, inflammation acts as a protective mechanism when the body is injured. However, inflammation causes pain, stiffness, and even increased muscle spasm (a protective mechanism). Even minor compression combined with inflammatory chemical mediators can produce substantial radiating discomfort.

Auto accidents and traumatic injuries can also result in disc damage or joint instability, sometimes overlapping with conditions seen in whiplash injuries, especially when force transfers through the spine.

What Is the Best Treatment for Sciatica?

Effective sciatica treatment begins with identifying the specific source of nerve irritation. Evaluation includes assessment of spinal motion, disc involvement, neurological function, and muscular balance.

Treatment goals include:

• Reducing nerve compression
• Improving spinal alignment and mobility
• Decreasing inflammation
• Restoring normal movement patterns
• Preventing recurrence

Most patients improve with conservative care when treatment addresses both mechanical and inflammatory contributors. Early intervention often reduces the risk that an acute injury will become a chronic problem.

Sciatica Treatment in Denver

Our office serves patients throughout Arvada, Denver, and Wheat Ridge seeking conservative alternatives to potentially dangerous medications or surgeries. All therapies are performed on-site to ensure the best possible treatment outcomes and reduce treatment time.

We provide:

• Free consultations
• Same-week appointments
• Insurance verification and assistance

By dealing with the underlying cause of sciatic nerve irritation, treatment focuses on long-term recovery rather than temporary symptom suppression.

Frequently Asked Questions About Sciatica

Q: What is the main cause of sciatica?

A: The most common cause of sciatica is inflammation from joint dysfunction (subluxation) and muscle spasms compressing a nerve root. Severe cases are most often the result of a disc herniation, which may require more invasive treatments like surgery.

Q: How long does sciatica last?

A: Duration varies. Mild cases may improve within weeks, while chronic or severe cases may require several months of consistent care.

Q: Can chiropractic care help sciatica?

A: Yes. Improving lumbar joint mobility often reduces mechanical pressure on irritated nerve roots.

Q: Is sciatica permanent?

A: Most cases are not permanent and respond well to conservative care when treated appropriately.

Q: Can sitting make sciatica worse?

A: Yes. Prolonged sitting increases pressure on lumbar discs, which may aggravate symptoms.

Q: When should I see a doctor for sciatica?

A: If symptoms include progressive weakness, loss of bowel or bladder control, or severe neurological changes, immediate medical evaluation is necessary.

Q: Does sciatica always involve back pain?

Q: Can exercise worsen sciatica?

A: Improper or excessive exercise may aggravate sciatica symptoms. Choosing the right low-intensity stretches and exercises can be very useful in speeding sciatica recovery.
