Ok, so I just had to share. I have a bad back. My lower back has been bad for years, due to disc degeneration and arthritis. I've learned to live with the pain. Recently my back has flared up terribly, including my upper back with either a pinched nerve or nerve damage. I was researching things I could do to help alleviate some of the pain and I came across this dohickey-thing you lay on which stretches your spine.
I didn't give it a lot of hope, but thought for the price, it was worth a shot. I've been using it for several days now and every time I get off of the thing, I can stand up straight with NO pain. I've been using it twice/day. It's supposed to simulate traction and although I cannot guarantee it will work for you, I can honestly tell you it's working for me. It's highly reviewed as well.
The price has been fluctuating up and down, but currently it's $16.40, which is about 75 cents less than when I bought it.
