Sciatica is a common condition that is caused by compression of the sciatic nerve, which runs from the lower back, down the leg, and into the foot. Common causes of sciatica include herniated discs, spinal stenosis, and piriformis syndrome. Chiropractic care can help to reduce pain and inflammation associated with sciatica by using spinal manipulation and other modalities to improve movement and reduce nerve irritation. With proper care, most cases of sciatica can be managed and the prognosis is usually good.
