What is sciatica?

Sciatica is defined as pain that radiates along the sciatic nerve, which is the largest nerve in the body. This nerve runs from the lower back through the hips and buttocks and down each leg. It is often caused by the compression of the sciatic nerve due to herniated discs, spinal stenosis, or other conditions that may affect the lumbar spine. The hallmark of sciatica is the characteristic pain that can extend from the lower back, through the buttocks, and down the leg, sometimes affecting one side more than the other. Understanding this definition is essential, as it helps in identifying the symptoms and underlying causes of the condition, as well as guiding treatment options. Therefore, the identification of sciatica as pain that radiates along the sciatic nerve aligns perfectly with established medical definitions and understandings of this condition.
