sorry to be a pessimist, but finding a reason for the neuropathy does not necessarily mean to better treatment.

My PN is caused by my lupus - I have had all the treatments available for lupus (including cytoxan and rituxan, the big guns) and it hasn't made any difference to my PN. Helps the rest of my lupus though.

So although it can be interesting to know what causes PN, it does not guarentee a treatment.
