Well sort of: Like I tell patients all of the time, if you have diabetes or a vitamin deficiency, then pinning down the cause of a neuropathy is easy. Anything else can be quite a challenge and there are literally hundreds of causes for neuropathy otherwise. I'm sure at this point you had a thorough work up, but seeking quaternary care (e.g. Mayo Clinic) is not inappropriate at this point
