I Am Having Treatment For Diabetic Neuropathy (feet). Over A

I am having treatment for diabetic neuropathy (feet). Over a long period of time I think I have been prescribed every thing known to man. Nothing! My foot dr. and I have decided to try injections. B-12, Zylocaine (sp),
Kenlog. The injections seem to be helping. Very hard to describe sensations and pain types to someone else unless they are going through the same thing. Any thoughts on this? Please.
