I was diagnosed as having "idiopathic neuropathy", and coincidentally my brother started experiencing neuropathy the same year. However, my brother has type 2 diabetes and I do not.
My Dr. put me on Gabapentin, assuring me that it would be the 'fix'. But he wasn't really listening to me, I am just experiencing numbness, and not the burning stabbing sensations that Gabapentin would address. I took the Gabapentin for 3 weeks even though I knew it would not aid the numbness; it was making me 'dull headed', and I couldn't afford to be that way at work, so I stopped. Have not heard of any cure for the numbness, so I've just gotten used to it. Thankfully the PN hasn't gotten worse.
