What Is Sciatica?
Sciatica is a pain pattern caused by irritation or compression of the sciatic nerve or its nerve roots. Symptoms may travel from the lower back through the buttock and into the leg. Numbness, tingling, or weakness can accompany the pain. Sciatica usually affects one side of the body.

Key Takeaways About Sciatica

- Symptoms can include tingling, numbness, or weakness.
- Sciatica is not the same as ordinary muscle soreness.
How Sciatica Works
Sciatica describes symptoms along the path of the sciatic nerve. The nerve begins from nerve roots in the lower spine and travels through the buttock and leg. Irritation can produce pain, tingling, numbness, or weakness along part of that path. Symptoms may change with sitting, standing, bending, or other movements.

Common sources include a disc herniation, narrowing around spinal nerves, or changes in nearby joints and soft tissues. A clinical evaluation looks at symptom location, sensation, strength, reflexes, and movement. The term describes a symptom pattern, so the underlying cause still needs separate assessment. Radiculopathy is a related term that refers to nerve-root dysfunction and may overlap with sciatica when the lower-spine nerve roots are involved.
From the Advanced Injury Care Clinic team
When we assess Sciatica during Back Pain Treatment, we review the symptom path and ask how movement changes the pattern. Our team also checks spinal and lower-extremity function to distinguish nerve-related symptoms from local muscle or joint pain. These findings help guide the next clinical step.
Sciatica in Practice: A Real-World Example
A person develops lower-back pain after lifting and later notices burning that travels through one buttock into the leg. The pattern may be described as Sciatica, especially when the symptoms follow a nerve pathway.
