There’s no way to “fix” sore muscles. You can take a warm bath, stretch, or put on some sports cream, but what if all you want is a hot wrap for one targeted area? You could always do the sock filled with rice trick, but that’s not exactly formed to fit your body.
The Place Anywhere Cordless Heated Back Wrap is a very thin, mild-compression neoprene wrap that will help you relax eight specific muscle groups: your back, neck, shoulder, elbow, abdomen, thigh, knee, or ankle. It uses a slim lithium-ion battery to function, and can be used for up to five hours on a four hour charge. It has a four-leveled temperature range of 95-120 degrees Fahrenheit, and costs about $150.
