Sciatica in State College

What Is Sciatica?

Sciatica is not a diagnosis on its own — it is a symptom pattern caused by irritation, inflammation, or compression of the sciatic nerve. The sciatic nerve is the longest and widest nerve in the human body, originating from multiple nerve roots in the lumbar spine (L4–S3), passing through the buttock, and traveling down the back of each leg all the way to the foot. When any portion of this nerve is compressed or irritated, the resulting pain can be felt anywhere along its path.

Understanding sciatica correctly is important because effective treatment depends on identifying the specific cause and location of the nerve compression — not just managing the pain. At Casteel Chiropractic, Dr. Casteel conducts a thorough evaluation to pinpoint exactly what is causing your sciatic nerve irritation and builds a treatment plan around that finding.

Common Causes of Sciatica

Sciatica can be caused by several underlying conditions, all of which Dr. Casteel is experienced in evaluating and treating:

• Lumbar disc herniation — The most common cause. A herniated disc in the lower lumbar spine can protrude and press directly on an adjacent nerve root, producing classic sciatica symptoms down the leg. Our Flexion Distraction technique is particularly effective for this cause.
• Lumbar spinal stenosis — Narrowing of the spinal canal in the lower back that compresses the nerve roots as they exit the spine
• Spinal misalignment (subluxation) — Vertebral displacement that places mechanical pressure on nerve roots or the sciatic nerve itself
• Piriformis syndrome — A condition in which the piriformis muscle in the buttock becomes tight or spasmed and compresses the sciatic nerve as it passes beneath or through the muscle
• Spondylolisthesis — One vertebra slipping forward over another, narrowing the nerve exit canal and irritating the nerve root
• Degenerative disc disease — Age-related disc thinning that reduces the space available for nerve roots in the lumbar spine
• Pregnancy — The growing uterus and shifting center of gravity can place pressure on the sciatic nerve. Learn more on our Treatments During Pregnancy page.
• Trauma from auto accidents or sports injuries — Visit our Auto Accident Injury and Sports Injury pages for more information.

Recognizing Sciatica Symptoms

Sciatica typically affects only one side of the body at a time and produces a distinctive pattern of symptoms that follows the path of the sciatic nerve. Common symptoms include:

• Sharp, shooting, burning, or electric shock-like pain that travels from the lower back or buttock down the back of the leg, sometimes reaching the foot
• Dull, aching pain in the lower back or deep buttock that may be constant or intermittent
• Numbness, tingling, or a “pins and needles” sensation in the thigh, calf, or foot
• Muscle weakness in the affected leg
• Pain that worsens with prolonged sitting, bending forward, or certain positions
• Difficulty standing up from a sitting position due to pain or muscle weakness

How Chiropractic Care Relieves Sciatica

Chiropractic care is one of the most effective conservative treatments for sciatica because it directly addresses the mechanical causes of nerve compression rather than simply masking symptoms. Dr. Casteel’s approach to sciatica treatment at Casteel Chiropractic may include:

• Lumbar spinal adjustments — Using the Gonstead, Diversified, or Thompson Technique to restore proper vertebral alignment and reduce nerve root pressure
• Flexion distraction therapy — Gentle spinal decompression that is highly effective for disc-related sciatica. See our Flexion Distraction page for details.
• Soft tissue therapy — Including Myofascial Release to address piriformis and gluteal muscle tension that may be contributing to sciatic nerve irritation
• Therapeutic exercises — Targeted stretching and strengthening exercises to reduce nerve tension, restore lumbar mobility, and build the core strength needed to protect the nerve long-term

Don’t Wait — Sciatica Gets Worse Without Treatment

Many patients make the mistake of waiting for sciatic pain to resolve on its own. While mild, acute sciatica sometimes does improve with rest, ongoing or recurring sciatica indicates an underlying structural problem that will not self-correct. Without care, nerve compression can worsen over time and become increasingly difficult to treat. The sooner you see Dr. Casteel at Casteel Chiropractic for a sciatica evaluation, the more treatment options you have — and the better your long-term prognosis.
