@pamelaz - I have not found anything that works for axonal sensory motor PN either. I found out by a neurologist at Mayo that Lyrica and Gabapentin actually can make things worse by an increase in gait instability. Oddly enough, I was prescribed Gaba but could not tolerate it. At first, I felt a decrease in numbness in feet. The negative side effect outweighed the small benefit so on the advice of Mayo, I stopped. Otherwise, like you, not much helps and I've taken many supplements with prior doc approval as suggested by mentor @johnbishop. Still, not much improvement. I feel supplements will help in many cases depending on the cause of the PN.
