What is Sciatica?
By Dr Liji Thomas, MD
Sciatica is the occurrence of pain in the thigh, leg and buttock, due to pinching of the sciatic nerve. This large nerve is formed from a number of smaller nerves, which leave the spinal cord between neighboring spinal vertebrae. Once they join, the sciatic nerve passes into the buttock, and then into the back of the thigh and the leg. It may be pressed against the underlying bone at different points on its journey from the spinal cord to the leg.
