I had excruciating pain for over a week, my doctor told me to ice the area and take pain pills, which provided no relief. Saw your product advertised and decided to give it a try. After first application, pain seemed to decrease immediately, after second, pain hardly noticeable, could sleep nights and put on my socks and tie shoes, product is great and will use it again. Plan to show my doctor at next visit, to a better way to treat hamstring pulls. Thanks for a great product and great relief. Therapy e-mails have been a great help also. Thanks again.
