Hi.. I have SFN in my feet... and Erythromelalgia... and recently became Diabetic type 2... I've had the hot burning pain in my feet for a very long time, then came the neuropathy.. After an appmt a couple of weeks ago with the Diabetic Nutritionist and trying something in her office that she said many of her patients swear by, I'm now using it all the time.. It has given me back a big bit of my life already and I am not having the awful pain when I stand or walk about my home.. Now I'm posting almost daily about my "experiment" testing it out.. It doesn't work for everybody, as Davidd has found out.. but it's defintitely worth a try for anyone with SFN or ER... I'm so thankful that it does work for me... just hope it continues... Blessings...
