Much of the diagnosis is based on the subjective complaint from the patient. Orthopedic test and other exam findings will help confirm the diagnosis. Imaging, such as MRI and x-ray films, may help find the source of the problem. One cause of sciatica is from disc herniation.
Disc herniation can occur when a spinal segment becomes so degenerated the disc is protruded outward. This outward protrusion can sometimes push out posterior and lateral to the spinal cord. When this happens pressure is applied to the spinal nerve root which can cause pain to radiate along the sciatic nerve. The spinal nerve root can also have pressure put on it from other conditions such as spinal stenosis, piriformis syndrome and muscular trigger points.
