Understanding the Condition
What Is Sciatica?
Sciatica is not a diagnosis in itself — it is a symptom set describing pain, numbness, or weakness that travels along the sciatic nerve, the longest nerve in the human body. Formed from the L4–S3 nerve roots, the sciatic nerve runs from the lower back through the buttock and down each leg to the foot. When any of these roots are compressed or irritated — most commonly by a herniated disc, bone spur, or a tight piriformis muscle — the characteristic shooting, burning pain follows the nerve's path, typically affecting one side. In Malaysia's desk-work culture, sciatica has become one of the most common complaints presenting to chiropractic clinics, yet it remains widely misunderstood and overtreated with painkillers that mask the cause rather than resolve it.
