I was suffering from a pinched nerve for over a year. I was even contemplating surgery. I saw the ad and decided to give it a try, it's free to try it after all. The first week was rough, but then in the second week, the pinched nerve was gone, and I fell a lot better, meaning, very little back pain. At the 30 day mark, my husband asked, so are we sending this back, my response was, I'm keeping it. Thank you Teeter for everything.
