I have used the Zopec device that John is referring to for quite a few years -- it is an electrical stimulus device -- I use it about a half hour every morning, sometimes a bit longer -- I don't have the pain just the numbness and stiffness in my feet/ankles/lower legs. What I feel it does for me is that it stimulates the blood vessels, and then I don't feel the stiffness as much. I didn't think it was helping, but then when we went on vacation, I didn't take it with me, and then I knew it was helping me
