Thats really surprising to me. I think a lot of these neuros get to a point where they will try anything. I get better relief just taking a small amount of Gabapentin at night and taking high doses of B1 and R-Lipoic Acid. That's what seems to work for me. I have even had very brief periods where pain is almost gone completely and I am not dealing with any other side effects. Its rare but it happens. Everyone is different, as bad as i think my pain is I have learned that there are folks in 10x the pain as I. It seems unimaginable and my heart goes out to those folks.
