Hi Majorcut & welcome to the forum, to get more exposure it's really best to post a new thread, but anyway, there are over 200 known causes for PN, it might help if you give more information, like what test's have been done so far besides Diabete's, have you been tested for prediabete's ? what was your b12 levels when tested ?, are you seeing a Neuro that is a PN specialist ? spinal taps, had an MRI on your back ? stuff like that may help.
