Symptoms depend on the location of the herniation and which nerves are affected; in the lower back, pain may radiate into the hips, legs, or feet (sciatica), while in the neck, pain may spread into the shoulders, arms, or hands; tingling, numbness, or muscle weakness are common signs of nerve irritation, and some people also experience sharp or shooting pain when moving; chiropractors assess posture, mobility, and nerve function to identify the affected area and provide care designed to reduce pain and restore normal movement.
