After having a battery of tests (blood work, EMG,etc.),
I saw my Neurologist yesterday for the results. I was
diagnosed with Axial Sensory Neuropathy but they still
cannot find the cause.

The next step is a nerve biopsy. Has anyone had that
and if so, was it helpful for your diagnosis?

This sounds painful to me, but if it helps to find the
cause, I guess I'll go for it.
