I was diagnosed with inherited SPN in 2004. Pain is well controlled with prescription meds but this last year I started having numbness increase in my toes and soles of my feet. I read about alpha-lipoic acid helping diabetic neuropathy in a research study and started it about 6 months ago. It has made a dramatic difference in 2 areas: my numbness is almost completely gone as long as I continue to take 600 mg twice a day; my back pain (nerve) is dramatically improved! I am no longer having to take Xstr Tylenol and Advil throughout the day for my back. I don't know if it will help the numbness in your feet but it has made a dramatic improvement my quality of life. Good luck to all of you who deal with daily health issues and keep your spirits up as best you can. Prayer helps me! And of course, positive people.
