Sarah i cant feel the tens machine in my feet either using it dry that is with the pads. Before you get a rebuilder try this. buy a divided foot bath, put in lukewarm water with epsom salts on each side. take the pads off of the leads of the tens machine. put one lead in each side of the footbath. i other words one wire into the water on the left side of the footbath and one wire in the right side of the footbath. keep the setting on the tens low at first and then raise it slowly until you feel the electricity. this is exactly how the old rebuilder used to work before they went to pads and socks. you can still see the type of footbath i am talking about on the rebuilder site in the photo for the physicians 2407 package. you can get the footbath in any drug store and if they dont have it they will order it. its entirely safe if you use the battery in the tens and not the electrical plug into the outlet. give it a shot, im sure you will feel it then.
