Hello,

I have non diabetic neuropathy since 2009. My symptoms progression follows pretty much yours. I took a lot of all sorts of tests blood, genetic, spinal and visited many neurologists at many places on the east coast - nada the diagnosis is idiopathic sensory-motor polyneuropathy. Last year the n-th neurologist prescribed Sensory (+- Motor) Neuropathy Panel with one of the tests being IgG vs FGFR3 - bingo ... and so what, no treatment available. My solution is exercise as much as you can, take no medication since it seems to only aggravate the damn thing, gadgets don't help, I keep Gabapentin as the last resort (I tried it for a couple days and it worked).
God bless.
