Good to know someone so active in this field will be posting and I look forward to seeing more. I have done a little research into Neuropathic Pain and Peripheral Neuropathy and the most authoritative article I have found so far on the web can be found by a search engine citing the terms: "Scadding ACNR Neuropathic" (I haven't yet made enough posts on this site to be able to post links). This review article is full of medical jargon but there is a lot of useful information about the causes and treatments of NP/PN that will repay the effort of deciphering.
Best wishes for your work.
