Sciatica is a generic term people use to describe nerve pain that goes down the leg. Most often this type of pain is not a condition at all, but is instead the result of a pinched nerve as high up as the low back. Chiropractors spend a considerable amount of time, working to identify the vertebrae in the spine that is the actual cause of the problem. Once this area is identified, the doctor can create a treatment plan tailored to your unique situation.
