Now, I read the instructions and they do instruct you how to use this for my problem. I found that looking up thera-bar on youtube brought me to several videos that helped me better understand the exact execution. The product worked great. It was really me that didn't stick with it towards the end..... I mean, it was feeling better so I faded away. Seems crazy, but I would recommend this.
