I just made a post about a battery operated heating brace that I wear for the RSD in my shoulder. The company also makes heated clothing of all sorts. The name is Venture Heat. The items are not cheap but I have used the same brace for four years and bought extra batteries so I have plenty on hand when I leave the house. The best heating pad I found is made by Sunbeam and is the "Shaped Flexible" design. It has velco straps and a timer control. I have literally wore out six of them in the last ten years but they are worth it. Here's to a "mild" winter.
