RELIEF WITHOUT PAINKILLERS: Our microwavable heating pad for neck and shoulders provides drug-free musculoskeletal relief, easing tension, calming inflammation, alleviating pain, and speeding up recovery from injuries or flareups. MOIST HOT OR COLD THERAPY: Our heated microwavable neck wrap can alternately function as a cool pack after an hour or two in the freezer. The surface moisture upon cooling or heating enhances the penetration of its therapeutic effect. WEIGHTED FOR LIGHT COMPRESSION: Target deeper structures under the gentle weight of our neck wrap. Microwavable human-grade flaxseeds inside weigh enough to exert slight, soothing pressure on painful areas while keeping the wrap in place. ERGONOMIC NECK WARMER: Microwavable heating pads by SunnyBay are specifically designed to provide comfort to aching body parts. The rounded edges and form-conforming stuffing make them feel more like warm hugs than pain relief accessories. VERSATILE FOR WHOLE BODY USE: While originally intended as a neck heating pad for neck pain or shoulder issues, our form conforming narrow wrap settles over any body part. Use for athletic injuries, arthritis pain, period cramps, and more.
