Sciatica is characterized by pain or numbness in the legs, feet, or buttocks. The condition is triggered when nerves in the lower back, sacrum, or leg are compressed or irritated. The cause of this irritation can often be traced to a misalignment of the spine or to a herniated disc that puts pressure on the nerve root, but the pressure may also be caused by obesity, pregnancy, poor posture, or some trauma. Chiropractors treat the underlying causes of sciatica by focusing on realigning the spine and working with clients to reduce weight, improve posture, and increase whole-body wellness.
