Sciatica is a term used to describe pain that radiates along the path of the sciatic nerve, which runs from the lower back through the hips and buttocks and down each leg. This condition is often characterized by sharp, shooting pain, numbness, or tingling that can affect one or both legs. Sciatica is typically caused by compression or irritation of the sciatic nerve, often resulting from underlying conditions such as a herniated disc or spinal stenosis. While the pain can be debilitating, it usually improves with conservative treatment, including physical therapy, medication, and lifestyle modifications.
