Be sure to seek out all the 'references' at the bottom. AND be FAMILIAR with all the terminologies [which I believe you are by now].

It should be easy for you to go yay or nay to many diagnostic aspects .. knowing the lingo and go from there.

Good luck! I've had it [tinnitus] since age 10, so, I can't be an expert vis-a-vis neuropathy only. Do check out allergic and vascular possibilities tho. They come into play significantly at times. And then? There can be the complications or aggravations by combining different meds for different problems... Do your homework and LOOK at all your med's side-effects! I've stopped MANY meds because of the s/e's and I'll state it out loud when necessary.

Good luck.... I'm going back under my hi-tension wires now. - j
