I can recall a number of members posting to say that various neuropathy type pains have improved while getting their blood glucose under control. Sometimes the pain gets worse before it gets better which may be a sign that the nerves are regrowing.
Off the top of my head, I can remember
@Jim Lahey experienced great improvements.

The key component seems to be getting blood glucose under tight control and keeping it there so that the damage can heal.
I also suggest you do a forum search for threads on neuropathy and r-ALA since this is a fairly frequent discussion and there are lots of people giving their personal perspectives and experiences on those threads.
Edited to add: my personal experience is that if I let my blood glucose swing too high and then back again for even as short a time as a week (e.g. on holiday) I start to experience stabbing pains in my feet. Once I get back to my normal routine and my bgs return to more steady readings, with a much smaller variation, the pains fade and disappear. I find it incredibly motivating to keep to low steady blood glucose, since the alternative is experiencing someone stick a red hot needle up into the sole of my foot at random intervals throughout the day.
