The searing, electric pain that runs from your lower back, through your buttock, and down the back of your leg is unmistakable. It might start as a dull ache and escalate to a stabbing or burning sensation. Bending, sitting, or even lying down can make it worse. This is sciatica — and it affects millions of Americans every year.

The good news: with the right diagnosis and the right care, most sciatica cases resolve. The challenge is that “sciatica” is a symptom, not a single diagnosis. Understanding why your sciatic nerve is irritated is the most important first step — and it’s where a functional chiropractic evaluation makes all the difference.

What Is the Sciatic Nerve?

The sciatic nerve is the longest and widest nerve in the human body. It originates from nerve roots in the lumbar spine (L4–S3), passes through the pelvis, runs deep through the buttock, and travels down the back of each leg all the way to the foot. When this nerve gets compressed, stretched, or irritated anywhere along its path, pain can radiate through the entire distribution.

Common Causes of Sciatic Nerve Irritation

1. Lumbar Disc Herniation

The most common cause. When the soft inner material of a spinal disc pushes outward and presses on a nerve root, it can create radiating pain, numbness, and weakness. This is confirmed through X-ray and clinical examination, and sometimes MRI.

2. Lumbar Stenosis

Narrowing of the spinal canal, most often from arthritis and age-related changes, can compress the nerve roots as they exit the spine. This tends to cause bilateral symptoms and is worsened by standing or walking.

3. Piriformis Syndrome

Often misdiagnosed as disc-related sciatica, this occurs when the piriformis muscle tightens and compresses the sciatic nerve as it passes underneath. Pain is usually deep in the buttock and worsens with sitting.

4. Sacroiliac Joint Dysfunction

The SI joint connects the pelvis to the sacrum and can refer pain into the buttock and leg that mimics sciatic pain. It’s frequently overlooked in standard evaluations.

“Treating sciatica without identifying the source is like treating a leaky roof by mopping the floor. The right diagnosis changes everything.”

How AFCC Evaluates and Treats Sciatica

At AFCC, we begin every sciatica evaluation with a comprehensive history and orthopedic examination — including nerve tension tests, range of motion assessment, muscle strength grading, and reflex testing. Combined with our on-site X-ray imaging, this gives us a clear picture of what’s driving your symptoms.

• Lumbar spinal manipulation to reduce disc pressure and improve joint mobility
• Flexion-distraction technique for disc-related cases — a gentle, non-force approach
• Soft tissue release and manual therapy targeting the piriformis, hip flexors, and lumbar musculature
• Therapeutic rehabilitation exercises to stabilize the core and take pressure off irritated nerve roots
• Trigger point injections or PRP with Dr. Syed Ali, MD, for persistent cases

Many patients with sciatica also deal with lower back pain that keeps coming back between flare-ups — a pattern worth addressing at the same time.

When Should You See a Chiropractor for Sciatica?

• Pain has lasted more than a week without improvement
• You have numbness, tingling, or weakness in the leg or foot
• Pain is severe enough to limit your daily activities
• You’ve tried rest and over-the-counter medication without relief

Signs Your Sciatica Needs Professional Evaluation

• Pain radiating from the low back into the buttock or leg
• Burning, electric, or sharp shooting pain
• Numbness or tingling below the knee
• Pain worse with sitting, coughing, or sneezing
• Weakness when lifting the foot (foot drop)
