I just been through this and have done tons of research.
Neuropathy starts when your BS post prandial goes higher than 7.7.
My neuropathy was so bad that I could not wear shoes and I could not sleep. The dr's put me on Amytriptiline but then I could not wake up in the mornings. It left me too drowsy that I could not function 100%
I went back to the dr who sent me to a neurologist and podiatrist. They then prescribed Gabapentin. I went to collect the pills and when I got home, i started reading the leaflet. There was no way I would take take these pills. I googled them and read many reviews. I did not want to feel like my brain is numb, halucinate or appear slow.
I then was advised to read 'The antioxidant Miracle' by Lester Packer. I bought the kindle version and started reading. I read the book cover to cover in a single day and was so inspired by the stories and research that I was reading.
I went to Holland and Barret and bought Alpha Lipoic Acid and Vitamin B12, Vitamin C, D and E. Tripple Omega and Co Enzyme Q10.
I started low carbing and keeping my bloods as low as possible. I did everything to avoid a post prandial spike. Within 1 week, my neuropathy pain was gone.
I now find that if I have a bout of high blood sugar, even if it goes up to 12 after a meal, the tingling and burning comes back. The other day I had a blood sugar or 26 and the pain returned even worse.
The ONLY way to treat neuropathy is to keep you BS under 7.7 and to take alpha lipoic and vitamin B12.
In Germany all diabetic patients with neuropathy are prescribed alpha lipoic and Vit B12.
I have also been reading stories about men in particular with neuropathy. Most of them have a degree of erectile dysfunction. Some of these men started taking viagra / cialis which improved the flow of blood into the microvascular veins which inturn also seemed to improve neuropathy.
Neuropathy is a serious condition and will only get worse if you just take stuff like gabapentin and do not deal with the cause. You really have to stay below 7.7 at all times.
Hope that helps.
