Sciatica refers to pain that radiates along the path of the sciatic nerve—your body’s longest nerve—which travels from the lower back through the hips, buttocks, and down each leg. This condition isn’t simply “back pain”; it’s a distinct nerve issue caused by compression or irritation of the sciatic nerve itself.
Unlike general lower back pain, which may remain localized, sciatica typically causes radiating discomfort that moves from the lower back down to the foot. The severity and type of symptoms can vary depending on the location and extent of the nerve compression, but for many, it becomes a debilitating condition that severely limits mobility.
