Backache pads, commonly known as heat or cold therapy pads, are designed specifically to alleviate pain and discomfort in the back region. They come in various forms, including adhesive gel pads, electric heating pads, and traditional hot or cold packs. They can be applied directly to the skin and are often made from materials that retain heat or cold for extended periods. Some advanced models even offer adjustable temperature settings, allowing users to customize their relief.
