Sciatica simply means problem with the sciatic nerve. Sciatic nerve is the longest nerve in the human body starting from pelvis passing through buttocks, thighs and backside of the leg and ending near the sole of the feet. Typically sciatica affects only one side of the body or only one leg.
Causes of sciatica
Compression of the sciatic nerve: When there is bulging (herniation) of disc or extra growth of the bone or bone spur of the vertebra it causes compression of sciatic nerve and this produces symptoms of sciatica.
Spinal stenosis: The narrowing of spinal canal puts pressure on the sciatic nerve and causes sciatica.
Trauma: When there is severe trauma to the body resulting in pelvic fracture it causes sciatica.
In rare circumstances the sciatic nerve can be compressed by a tumor or damaged by disease such as long-term diabetes.

Diabetes: Long-term diabetes can damage the sciatic nerve and cause the disease sciatica.
Diagnosis of Sciatica
Sciatica can be diagnosed by conducting following tests on patient.
X-ray of the spine
Magnetic Resonance Imaging (MRI): MRI helps in producing detailed images of bone and soft tissues and thus helps in diagnosing the case.
Computerized tomography scan (CT scan): In this particular test a contrast dye is injected in the spinal canal and X-rays are taken then after.
