Sciatica represents an underlying health condition and manifests through pain, numbness, weakness, or tingling starting in the low back and radiating down the large sciatic nerve in the back of either leg. People suffering from sciatica detail a feeling of pins and needles tormenting the body at varying degrees of pain and discomfort.
