Check out the stickies at the top of the page - there's a tremendous wealth of info for all types of neuropathy, causes (where they can be determined and are not idiopathic), diagnoses, treatments, benefits of dietary supplements, vitamins, etc, etc. In addition, try this link too - it's a good start that can connect you to a great deal of infomation too.

I'm sure many other forum memebers will give you links to other sites of info so be patient for a bit. There are also many members who are very well versed in worker's comp, disability claims and the like so I'll defer to their experience and expertise.
You've come to the right place for help, support, and information.
