How many HeatWraps can I use at one time? Sometimes I need help in more than one area (like my knee and my shoulder).

You can safely wear more than one ThermaCare® HeatWrap, but do not wear more than one HeatWrap in the same location. Take precaution not to overlap heat cells or wear any HeatWraps under tight-fitting clothing, belts or waistbands. Check your skin frequently during use, and if you find irritation, stop use immediately.
