Sciatica is a condition that causes pain along the path of the sciatic nerve, which runs from the lower back through the hips and down each leg. This pain can range from mild to severe and is often described as a sharp, shooting sensation. It usually occurs when the nerve is compressed or irritated, often due to a herniated disc, bone spur, or spinal stenosis. People with sciatica may also experience numbness, tingling, or weakness in the affected leg. While the pain can be debilitating, many cases improve with time and conservative treatments like physical therapy, medication, or exercise. In more severe cases, surgical options may be considered.
