Sciatica Explained: What Is Really Causing Your Nerve Pain

Sciatica is one of the most common, and most misunderstood, forms of back pain. Rather than being a diagnosis itself, sciatica is a symptom of an underlying issue affecting the sciatic nerve, the longest nerve in the body, running from the lower back down through each leg.

What Causes Sciatica

Several conditions can compress or irritate the sciatic nerve. A herniated disc, where the soft cushioning between spinal vertebrae bulges or ruptures, is among the most frequent causes. Spinal stenosis, a narrowing of the spinal canal that puts pressure on nerve roots, is another common contributor, particularly in older adults. Piriformis syndrome, involving tightness in a small muscle deep in the buttock, can also compress the nerve as it passes nearby. Even prolonged poor posture, especially extended sitting, can contribute to nerve irritation over time.

Recognizing Sciatica Symptoms

Sciatica typically presents as a sharp, burning, or shooting pain that travels from the lower back through the buttock and down one leg. Some people also experience numbness, tingling, or muscle weakness along the same path. Symptoms often worsen with prolonged sitting, coughing, or sudden movements, and may improve somewhat when lying down or walking.

Why Rest Is Not Always the Answer

A common misconception is that sciatica requires complete rest. In reality, prolonged inactivity often worsens the condition by increasing stiffness and reducing blood flow to the affected area.

Appropriate, guided movement typically produces better outcomes than staying still.

Effective Treatment Approaches

Gentle stretching targeting the piriformis muscle and hamstrings can relieve pressure on the sciatic nerve. Core strengthening exercises provide better support for the spine, reducing the likelihood of nerve compression. Postural correction addresses one of the most common underlying contributors, particularly for those who sit for extended periods during the day. Achieva Rehabilitation's Back Pain and Sciatica Treatment program combines manual therapy, targeted strengthening, and posture education to relieve pain at its source.

The Role of Posture and Ergonomics

For those whose sciatica is aggravated by desk work or prolonged sitting, addressing workstation setup can make a meaningful difference. Simple adjustments to chair height, monitor position, and sitting duration, combined with regular movement breaks, often reduce symptom flare ups significantly.

When Sciatica Overlaps with Other Conditions

Sciatica like symptoms sometimes appear alongside other conditions affecting movement and gait, including neurological disorders. Our related Neurological Physical Therapy page discusses how altered movement patterns can contribute to secondary pain issues like sciatica over time.

Additionally, because sciatica can affect balance and increase fall risk during flare ups, our Falls & Balance Physical Therapy program offers complementary safety strategies.

The Value of Professional Evaluation

Because so many different conditions can cause sciatica like symptoms, an accurate diagnosis is essential before starting treatment. A thorough evaluation helps distinguish between a herniated disc, spinal stenosis, muscular causes, and other contributors.

Frequently Asked Questions

Is sciatica always caused by a herniated disc?

No. While herniated discs are a common cause, spinal stenosis, piriformis syndrome, and muscular imbalances can all produce similar sciatic nerve symptoms.

How long does sciatica typically last?

Duration varies widely depending on the cause. Some cases resolve within a few weeks with appropriate treatment, while others require more extended care, particularly with structural causes like disc herniation.

Should I avoid exercise if I have sciatica?

Complete rest is generally not recommended. Gentle, guided movement and specific therapeutic exercises are usually more effective than inactivity.

Can sitting all day really cause sciatica?

Yes. Prolonged sitting increases pressure on spinal discs and can contribute to nerve irritation, especially when combined with poor posture.

When should sciatica be evaluated by a professional?

If pain persists beyond a few days, worsens over time, or is accompanied by numbness, weakness, or loss of bladder or bowel control, prompt evaluation is recommended.
