--that you tend to feel symptoms more when standing or still than when moving; when you are moving other sensations likely interfere and help cancel out the unpleasant ones you have now (which does imply that your neuropathy is not that severe, at least yet).

Also not surprised that you're having trouble with SSDI--the system is pretty much set up to deny people the first or second time until they can get lawyers and documenting doctors into their corners.

The definition of "mild" neuropathy is pretty ambiguous--people with minimal degrees of damage to nerve fibers as revealed by biopsy can still have terrible symptoms; often, partially damaged nerves produce worse symptoms than "dead" ones, as the brain has trouble interpreting the garbled, erroneous signalling.

We do have an SSDI forum (don't know if you've seen it yet):

There's good advice there on how to present your symptomology in order to have the best chances to be granted disability.
