--with so many nerve symptoms is that they may have many different causes.

For instance, sensory and motor symptoms may stem from problems with the brain, the spinal cord, or the peripheral nerves, and the symptoms may be exactly the same. And--the number of conditions that cause nerve damage that feels similar are legion.

This is why the testing for such symptoms is often a long, expensive process of elimination.

This is part of the reason I highly recommend the spreadsheets at www.lizajane.org to list and track tests. The charts are about as comprehensive as is possible regarding tests for neural symptoms, and many of the tests can shed light on a large range of other possible conditions (hormonal disregulation, metabolic disorder, circulatory problem--in short, anything that might affect nerves) as well.
