Hello, Has anyone tried that thing seen on infromercials- It is a device that sends electrical currents into the muscles, it is support to releave pain and distribute oxygen better? I have one, on a trail basis from a friend. And I do find it relaxing. It was a mistake to put it on my chest muscles though, that just caused chest pains, but it does seem to provide some relief to other areas (neck). In some spots it does nothing for me (back), and when I put the electrodes on my upper arm it made my wrist hurt. So I was just wondering if anyone has gotten good or bad result from these things. I know, way back when, when I was in physio-therapy they used a device very similar- so I am assuming it does some good it you use it long anough.
