You are trying so many things ….alas to no avail you did not however mention reflexology, I am experiencing some relieve using that modality 2x a month and a massage gun nightly. I quit taking the gabepentine just masks the nerves for me, I want to feel my feet sorry but neurologist are now a waste for me, I still use turmeric (helps with inflammation) and vitamins as well. Good luck to you !
