Welcome to Neuro Talk. Glad you found this site. You will find some good information here, as well as compassion. I have PN in my left foot and ankle, calf. Have you tried a physiatrist? I use a lotion that has Ketamine in it, with several other medications, which really numbs the area, and no burning. It doesn't feel good to rub in, but after words it really does provide some relief.
A physiatrist, deals with pain, AND the whole body on a cellular level. This doctor has helped me to get some relief. Keep in touch. We do care about people on Neuro Talk. You will make some friends along the way. Feel free to join in on any conversation, on any forum. ginnie
