Im sorry for butting in, but something you said struck me.
I receive weekly lidocaine infusions and get partial relief although I will agree it is short lived. When I stopped for one week I realized how important they are, regardless.
I question myself all the time about the joy of having partial pain reduction and why cant it be more or last longer. Mind you I still need to take Hydrocodone (along with Cymbalta and Lyrica) but, it manages my pain better in conjunction with lidocaine.
I try my best to just be thankful and not focus on what lurks around the corner each week after my few "better" days are up. So, I agree with your "get greedy" statement. Hard not too when starved for relief.
My neuropathy seems to be different in the fact that I have wide spread pain through my body and it is not contained to my feet.
I suppose trying lidocaine is about what it's worth to you. I'd hope it would bring your feet some relief, albeit temporary.
Not gonna lie...this rollercoaster of neuropathy is really wearing me down mentally and physically.
...insomnia at its best! I'm usually a very positive person.
