Thera Pearl is a product to combat inflammation. Consisting of gel-like "pearls" contained in a transparent plastic case, the polymer is equally adept at retaining either heat or cold depending on the application.
The versatility of hot or cold in the healing process makes the product well suited to therapy - a couple of hours in the freezer or a brief zap in the microwave allows for extended relief. Its clever design makes it functional, a hook and loop strap keeps the gizmo in place, and there are two types for overuse from running - one for the shins and another for knees, so one of each would serve you well.
