It not only sounds like you are in pain, but also like a diagnosis was given without a lot of testing and examination (what kind of tests have you had?).

Neurological problems in the lower extremities are often difficult to diagnose, as problems with the central nervous system--brain and spinal cord--problems with the nerve roots in the lumbar or sacral spine, or problems of the peripheral nerves farther down the legs can often result in exactly the same symptoms, and this can mean a lot of specific imaging and testing to try and pinpoint the problem area.

You should definitely come on over to our neuropathy forum--lots of sympathy and good information there:
