An explanation of sciatica including causes and treatment options.
The pain known as sciatica (sometimes misspelled as “syatica” or “psyatica”) is caused by irritation of the sciatic nerve (one on each side). The symptoms of sciatica usually start in the buttock and may extend partially or all the way down the leg. The sciatic nerves are each formed by nerve roots from the lower lumbar and sacral parts of the spinal cord. The individual nerve roots come together in the lower pelvis to form the sciatic nerves. Each sciatic nerve then runs from the pelvis down the back of each leg. The sciatic nerve splits into two parts below the knee and the two halves run down the back of the lower leg to the foot.
