“The Largest Nerve of the Body”
Pain is caused when the sciatic nerve roots are irritated, scraped, twisted, stretched or pinched as they exit the spine. Causes of the impairment may be chemical, physical or the emotional stress of everyday living. Full-blown sciatic flare-up can involve the entire sciatic nerve path resulting in symptoms of lower back pain, burning, cramping or numbness that radiates into the thighs, legs, ankles, feet and toes. Pain may also be limited to various points along the nerve, such as the buttocks, knee area and calf.
