I've probably overstretched the tendon on the thumb, which was very unpleasant. By rail loaded the thumb is not as fast and is also reminded to save him. It think I took a two weeks, but it has given back. The product is already a great help with such problems. Although the right to be applying only found out something. One tends to lash anything too tight. Although it is a steep price, but there is an odorless and well-made product.
