Sciatica is a term used to describe pain that radiates along the path of the sciatic nerve, which runs from your lower back through your hips and buttocks down to each leg. It's usually caused by a herniated disc, bone spur, or narrowing of the spine that compresses the nerve. Common symptoms include sharp or shooting pain, tingling, numbness, or weakness in the affected leg. Treatment can involve rest, physical therapy, pain medication, and in severe cases, surgery. It's important to consult a healthcare professional for an accurate diagnosis and personalized treatment plan.
