What Is Sciatica?
More than half of Americans will experience sciatica in their lifetime. Usually occurring between the ages of 45 and 64, sciatica symptoms are characterized by low back pain that radiates into the legs and feet and is often accompanied by numbness and tingling in the feet and toes.
90% of sciatica cases are the result of a herniated disc in the lumbar spine, or lower back, that causes compression of the nerve root resulting in the odd symptoms such as the numb or tingling toes. Other risk factors for sciatica include excess body weight, height, mental stress, diabetes, prolonged sitting, smoking, and occupational factors such as driving and high physical activity such as bending and twisting.
