Sciatica refers to pain that radiates along the path of the sciatic nerve, which runs from the lower back through the buttocks and down the back of each leg. It is not a medical condition itself but rather a symptom of an underlying problem affecting the sciatic nerve or its roots in the lower spine.
Sciatica typically manifests as pain, numbness, tingling, or weakness in the lower back, buttocks, and one leg, often extending down to the foot or toes. The pain can vary in intensity, from a mild ache to sharp, shooting pain that can be debilitating.
