Cyclelops, like the name too , but i just wanted to say that when a doc in his surgery tested me for diabetes, nothing showed up, she said " you certainly have got no problems with any diabetes " but in the first and only batch of tests that my neuro done he ordered a Glucose Tolerance test, the results come back as i was prediabetic.
To many docs world wide are still under the impression that you have to have full blown diabetes to get PN, which is not true.

eg -I had a hip replacement not that long ago and you know how an anesthetist will go over all your medical records before an op, well when i told this guy who had a student with him, that i had PN caused through prediabetes, he said " no way you have to full blown diabetes for a long time before you get PN out of it " so i said would you like to phone my neuro and tell him that ? he is Associate professor of neurology Dr.........., at our largest teaching hospitals in our state, i think he is the head of the neuro department & specializes in PN as well, he jaw just dropped and said " i really don't want argue with you. , i said " neither do i, your the doc mate but your very wrong about this " i think i might have brought him down a peg or two in front of his student.
This does worry me though with the medical profession, i wonder how many PNer's are out there that are classed as Idiopathic, and are suffering needlessly when they could be treated and eventually curred in time.
all the best
